I can't stop being angry at my mother and I hate myself for it
Why are you angry at your mom?
I feel that I'll never be as successful as my parents and I've always put up this front that I'm doing well.
While it is good that you are driven to be successful, it shouldn't be something that consumes you. You should learn to accept yourself and not compare your position in life with that of your parents. Talking with a therapist could be a good idea to help you get over your self-doubt and anger about your mother.
I should never have to suffer because of my parents. Fuck therapy.
Therapy could really help you. You seem to have a lot of unresolved anger and it is healthy to deal with it.
