Maybe you need to cleanse yourself and surroundings?
Give this a try I Am's Solar Grounding & Banishing Ritual
Another way is to cleanse yourself through showers and baths. If I’m feeling negative or just down, I’ll take a hot shower and cleanse my mind, body, and soul. Inhale and exhale deeply, and imagine all the negativity, anxiety, and depression that your feeling as a black goo covering you. Imagine the water as light. As it moves and flows across your body, see it washing away all the pain, sadness, and negative emotions that your feeling, imagine it going down the drain, leaving you for good. You can do the same with using soap as the “lifter” that breaks through this “black goo”. Finish by visualizing yourself clean and shining with a white light that emanates in and from you. I usually think to myself, “Nothing can hold me or influence me unless I allow it” or something that has special meaning to me. I’d advise you to find a mantra that resonates with you specifically.
Another thing I would 100% recommend you to do is integrate this specific meditation into your daily routine from @C.Kendall’s Soul Travel guide
Now if you want to work with some of the Gods and so on to empower you and help you, I’d recommend Lucifer before anyone else personally. Definitely someone who always wants to help those who truly want to be helped, especially dealing with depression and negativity in their life.
