Okay I’m going to type a reply based on stuff I’ve learned from various teachers and also what’s worked for me at extremes, and obviously this can’t address the medical/psychological aspects of depression, it’s just some ideas from a magickal/self-help point of view, and if it goes wide of the mark then I’m sorry and wish you the best! 
Obviously, I don’t know everything and my own life isn’t perfect, plus what I’m about to describe probably amounts to intentional insanity, so with that made clear, I’ll get started:
I believe that the first step for you to take is to create an inner sanctuary using your imagination, because the manifest world around you right now sucks. There’s not much you can do about that, and simple “happy thoughts” won’t do shit.
We have some friends who just moved to Greece to be with their family, and bad as the recession has been in the UK, southern Europe seems to be in a world of pain compared to us.
So IMO what you need to do is first, make yourself a secure base to place your emotions, your identity, and your focus since your external world is contaminated by poverty and depressing things.
Your imagination can create a secure base that no-one else can touch, and which will give you the fulcrum point from which to begin operating as a magickal and resilient individual, and you do that by an act of will and an act of creation - so, you’re already on a dynamic pathway away from despair and accepting what’s been given to you so far.
Let me give you an example - create for yourself an imaginary villa, or a luxy condo apartment, or if you want to aim high, have a castle or palace.
I like to keep my visualisations quite low-key, but you might find liberation in going to an extreme, and having a white marble palace with minarets and gold-plated balconies - so long as your heart sighs a sigh of relief when you think about it, there’s really no wrong way to do this.
Google “amazing interiors” and stuff like that for ideas - here’s one I like a lot, that’s pretty believable:
I like books, you might not, so choose the decor you prefer.
And remember there are no limits, so long as it makes you happy.
If you want, create a plausible backstory of how you got it - unknown uncle died and left it to you, weird freakish lottery win, or you did a favour for a wounded Knight elf and he left you a portal to his realm and castle.
Maybe your great-great-grandfather saved the life of an Indian princess, and now you’ve inherited a small tropical island in the Indian Ocean, with nothing but an old villa and some domesticated goats?
If you don’t feel like your imagination can handle creating something from nothing right now, which is fine (this is meant to be fun and not testingly hard work with an option to fail), choose a TV show that’s centred round a specific set (like Big Bang Theory, Friends, Frasier, whatever), and make that real, and then give yourself a simple backstory for why you’re there - maybe Frasier’s taking the family for a 9-month round-the-world cruise and you’re housesitting for him, with a generous weekly allowance, for 9 months.
Whatever you can live with, without too much friction or effort.
Create within this two rooms as your main bases, one to relax in (ideally a bedroom, or maybe a hammock, or whatever), and one to do focused thinking in, which may also become your astral temple later on.
Imagine the interiors (or balconies, gardens, whatever you chose) and imagine yourself walking round them, lying on the couches, relaxing in the rooms. Take time out for this, like making an appointment with yourself, because you’re creating something here and not “wasting time” with idle daydreams. This has a purpose.
That’s the first stage because it’s giving the creative mind within yourself a break, into relative luxury and also away from the immediate needs of your situation.
It also doesn’t have reminders of present problems, and it gives you a break from real friends and family who, no matter how much you love them, are caught up in the current of present-day events, and are probably as worried and depressed about them (and legitimately so) as you are.
~~
Stage 2:
Make a commitment to wake up “into” your luxy, safe, and liberating sanctuary at least twice a week, and by that I mean whatever your living circumstances, wake up and imagine you’re there. Try to wake a little earlier if necessary, so you can stay in bed and visualise this.
If that sounds weird, imagine how much differently you’d feel waking up here (or any of these bedrooms), every day:
You’d be getting new messages about who you are, what you can expect from life, what you’re capable of - you’d probably even stand, talk, and breathe in a different way…
You walk into the kitchen in whatever you’d wear in that reality, and you make yourself breakfast (or whatever other morning rituals you have) in that environment.
The brain seems to be more impressionable close to sleep, so doing this impresses upon your mind (the machine by which you have the potential to manifest a new reality) that sometimes, things can be cool, enjoyable, non-stressful, and not tied into lack and poverty.
Also, make it a project to find, make, or buy, anything at all that reinforces the existence of your sanctuary when you’re either waking up, or about to sleep - if you have a tropical island and can download rainforest sounds to fall asleep to, or wake up to a screensaver of the apartment/palace you wanted, or have for breakfast one thing (even if it’s just a coffee mug) that you’d have in that world, those will help make it one step more real.
Try to find some music, a piece of clothing, and anything else visceral that affirms the validity of your sanctuary, as well. Keep a folder about it on your computer or phone if you can - this isn’t a “vision board” - this is creating space in your internal reality, so don’t focus on the gap between these and your current situation.
And above all, NEVER envy or resent the people who actually own them - that’s some really bad mojo!
From here you’re going to be ideally doing this enough that your sanctuary becomes a real place to you, real like memories are real, and emotionally engaging like daydreams are - you’re creating and maintaining a place to retreat to, and relax for a bit, and (“It is like In my case i can tell that is exactely like you said. I am out of alignment with who i truly am, and that is because of the environment and people. I wished for a simple life, creating art, music”) to be who you truly are.
Set up an easel there (and keep a notepad handy IRL, also a “record” function etc), and imagine freely the art and beauty you create in this free and unlimited sanctuary.
~~
Phase 3:
The purpose of the above is that you attune your energy with safety, abundance, supply, opulence - that you create the vibrational and emotional resonance in your mind of something better than what the world outside is doing right now.
Try to do it a minimum of 2 days a week, more is better - and try to fall asleep thinking about it, visualising yourself in it, as well.
I did something like this, in a haphazard way and not on purpose, a few years ago when I was at my lowest and ended up living in the exact apartment my imagination had seized upon! This might be harder if you visualise a golden palace, but you never know.
Once you feel a genuine lift at the idea of going to this sanctuary, you’re ready to begin more conventional work, by which I mean opening sigils, or performing evocations (including in your sanctuary, as an inner temple) and also you’ll have raised your own state by giving your mind an escape from the manifest insanity around you right now.
Good spirits to contact at this point would be:
-
Hathor, who loves luxury and pleasure and also the arts, and she’s also the patron goddess of miners and foreign travel, so she might help you to literally dig out or discover some hidden break that will get your career back on track;
-
Buer, who hates to see people suffering and is committed, in my experience, to helping with any problems that are causing you anguish;
-
your ancestors, if possible - there are plenty of guides about this on this forum. I don’t know if you imagine yourself being a parent one day, but ancestral spirits hate to see their children, their future, in these kind of dead-end traps and will often pull strings and go to some lengths to help you out;
-
Belial, for assistance in doing what he said during the evocation E.A. did last year, that’s online here:
“Seek ever for your kingdom, your empire. Concern yourself not with those who are weak of mind, and who seek excuses to flee from their power. You are God now. All of you are God now. Favour the bold, the strong; favour those who favour you, and erase all others from your destiny.” ~ Belial
-
look into making a Jupiter Talisman, -TWF- on here has posted some ideas about this, and Jason Miller’s book “Financial Sorcery” has some new seals for different aspects of financial good luck, as well - but the basics of making a talisman are findable online;
-
consider reading the book “The Science Of Getting Rich” by Wallace T. Wattles - it’s freely available online in different formats because it’s out of copyright, and so is Napoleon Hill’s masterwork “Think And Grow Rich.”
That’s all I’m going to post for now, you might not like this style of doing things so I won’t go on: if this does seem interesting then first, see how you do with creating the inner sanctuary, then research some of those spirits and book ideas, and get back to me if this is working and you want to hear some other proposals - but if this honestly looks as useless as a chocolate teapot then I understand that, we’re all different, and I wish you the very best with whatever you do.
