Bless your heart -- I'm sure it IS hard to deal with him. It's hard enough having your own mental issues, let alone having to deal with a parent who has one too.
Is your father under the care of a therapist? Are YOU under a therapist's care? If not, you should be.
If you're NOT in therapy, see if you can get into therapy. Have your doctor refer you to a good therapist. If your dad has insurance that covers you, it might cover mental health too. Ask him about it.
I don't know how old you are -- if you're still in school, talk to your school counselor. He/she will understand and can help. You need someone to talk to and badly. So give it a try, okay? And if you'd like to just "talk" you can message me anytime. I'd be happy to listen, okay? I'm a great listener.
Take care, and keep us posted on how you're doing okay? Hugs, Lee
