Banish and cleanse. Then see if you feel better and continue from there.
There’s nothing wrong with your manifestation ability, looks like: you want to fix the sabotaging that’s going on.
The first obvious culprit for this is energetic parasites.
You’d probably suspect it by now if you were cursed by someone you know: you can feel the hate from them and you will naturally avoid them even if they don’t tell you (does anyone hate you that much?) or if your whole family has the same issue then it could be generational curse. If it’s based on living location it could be a curse in the land that may or may not be able to follow you.
It’s a matter that needs to be troubleshot by a process of elimination.
First fix the obvious and get your spiritual hygiene (tutorials above) and start getting your psychic skills up to snuff (everyone can do this, it’s a matter of pracice), then take stock,if it’s not enough yet keep going with the investigation, once you know what it’s not then what it is can come to light.
Only work with named entities that you yourself summon, no randoms, banish all randoms, all the time.
None of the Goetia are actually “demons”. They’d old gods, some are angels and some are human made egregores. They exist to help, as do the angels that made it to the church’s whitelist. But as you know, taking the churches word for anything isn’t sensible, so why do it for so called “demons”?
Randoms can be more like what you know as “demons”, they can be worked with but I’d say don’t try. I call those “parasites”, because they make you miserable in order to feed on that negative energy you make. I don’t use the word demon, the church made it meaningless on purpose to confuse people: be specific about what youre dealing with if you can, “demon” is not a specific enough word to be helpful: that’s like saying “human” when you mean “lawyer”. 
This needs investigating sooner rather than later. It sounds like your energy is blocked (and I mean literallty the energy channels in your body are clogged up, like blocks in blood vesselscause problems too. You cannot ground properly or connect to the cosmos and your energy stagnates and gets cold and sticky like this.) Picking up an energy working practice and learning how your body’s energy works will help a lot. This sort of thing goes hand in hand with being parasitised or cursed and one can be caused by the other.
Get the banishing done as a matter of urgency, set up your wards and get your space clean and clear of parasites. This is called “having good spiritual hygiene”.
Some heavily religions families attract these in droves through fear. Because their behaviour is controlled not by personal responsibility and doing what’s right but by fear of punishment: it’s very negative energetically, which is yummy to lesser entities and it’s not uncommon for prior catholic and related extreme religion refugees to have this issue. Seems like trying to leave that sect triggers an apostate reaction that forces some back into it. It’s a very evil cult, basically. The more I study it the more I see this kind of thing. It’s not your average JCI religion and gives you zero tools to recognise and fix problems with the unseen, I suspect on purpose: you are only allowed to go through the controllers for that to keep you dependent on the church, everybody knows is except the people in the cult. Banish and then banish some more.
Again, reevaluate this after a good round of banishing and getting your living pace clear.
Excercise to get info:
Sit quietly in meditation (just a thoughtful, serene state), ask yourself a question like “is a parasite attached to me?” and write down without questioning or thinking about it the first thing that comes to mind. Practice that and trust it. Keep asking more questions. You are training your subconscious to communicate with you and tell you what’s going on, because it’s connected to all and knows. The more you do this, the better it gets and your subconscious, which isn’t used to being listened to, learns to talk to you the way you can hear it.
