Hello, ljv90, and welcome to Psych Central! We are fellow "sufferers" like you, so we can't diagnose, but from my own experience, it sounds to me like underneath it all you are dealing with low self-esteem.
You've certainly been through enough tough things to justify feeling grief and depression. Please don't be too hard on yourself. Now, you deserve to have some fun and pleasure. What did you enjoy doing before all the bad things started happening?
I enjoy the social groups here and even playing the games. I also read, watch certain shows on TV, write, go to movies, shop, get out with friends, etc.
Again, welcome! You can make friends here as well.
P.S. And also complain about things like your mom undermining your parenting.
