How I deal with depressive, self-loathing thoughts

I feel like I just make myself hate myself in every way possible. I purposefully look up things I know will upset me, I look up bigotry towards people like me, telling me I am stupid, I am useless, I am a sin and shouldn't exist, I shouldn't be seen as a human. And it just adds to my depression.

What I do is to ask myself a stupid question, "Is this hate and negativity towards me gonna make me rich so I can buy whatever I want?" Nope it won't. So its useless and unhelpful and I couldn't care less. I do this with my own thoughts of self-hate that come out of nowhere, like "you are stupid and dumb and you can never be rich or earn anything" is that thought gonna help me? Nope. So I don't have to care about it.

its not easy, its keeps bugging my head, but the less and less importance I give to these thoughts, the less I'm stuck in something I call a "negativity thought loop". It's when I repeat, the bigotry, the hateful comments, the demeaning, insulting and belittling comments I hear and tell myself on a daily basis over and over and over in my head. It reduces my self esteem, my happiness, so I keep practicing this "will this make me rich?" question so it will keep me grounded and I can focus on the present and on my own, small world, which is more important than anything else and anybody else.
