My mom wants me to go to therapy what should I do?

I am really tried of my family. My parents are divorced and I have trouble at my dads house because of his drinking issues but now my mom want me to talk to a therapist about this and I know it not healthy to keep it in but that is what I have did for my whole life and now everyone is starting to care about it and I just want to keep it to myself because I think everyone will judge me, put it of ,or say oh mine is so much worse. I have also done therapy before but it did nothing it just made me avoid my parents. I am so tired of this, what should I do?
