I am starting to think that my mental health is not in the place it should be for magic. I am finding that on my good days I 100% believe and on my bad days I doubt all of my efforts and I might as well not have done the spells in the first place. I am feeling as though that is the reason I'm not seeing anything come to fruition (or the fact it's only been a few weeks since I began) but I feel like even though I read you're generally supposed to let go and let the universe do what it does I feel like the only way for me to believe is to hang on to it. If I let it go it may as well not be working, and then I doubt, and then I get depressed, which makes me doubt further. It's like my mood doesn't stay high enough long enough for anything to work because it goes back down and I doubt and essentially cancel out everything I'd just done after only a day or two and am not giving anything a chance to even work. And as I understand magic doesn't work instantly I feel like I need to stay positive long enough to give the universe a chance and I'm just not doing that.
I am currently feeling the lowest I have in a few months. I was in a really good place for a while there and even everyone around me noticed I was more lively and more cheery but today it's just like I want to climb into my bed pull the blankets over my head and stay there for a very, very long time. I want to cry but I'm not sure what about. I almost want to give up on my efforts. I looked into magic as a way to get the life I feel I am deserving of, but when I get this low it's like do I really deserve what I'm wishing for? And I feel by even asking that, by even questioning if I deserve what I'm asking for in my spells, I'm immediately canceling everything out. I am having fun with magic and when I'm in a good mood I feel great and like everything is working and then I just crash and I'm not sure why I'm even trying.
I can't be the only one in this situation, or who has gone through this, so how do you keep believing when you feel you can't? I'm thinking I should take a break and just relax for a few days, or go to a doctor I'm not sure

I've dealt with the ups and downs of my mood for about half of my time alive so I'm not asking for any sort of mental health help, but more how do you manage to do magic when your mental health is not well?
