Does having BP interfere with your family life? Does your family suck?

My family sucks. They're not understanding of mental illness at all.

My paternal grandma has dementia (yes, technically a neurological condition, not MI), and all my dad does is yell at her. He tells her to stop talking and to "go sit somewhere". He's rather mean to her and she gets very, very upset, often to the brink of crying. He's not understanding at all, and he seems to treat her worse now that he knows she has dementia.

Together, my parents make fun of MI and anyone who has to go to therapy. They think "therapy is for nut jobs". Then they laugh about it. My dad even made some horrible comments about schizophrenics and people with BP. "Bunch of nut jobs... This is why we have criminals out running on the streets. They're all schizophrenics and bipolars. They pull the disability card to get out of jail." And he continued to repeat the same things over and over, as if he didn't get his point across already.

I get to look forward to listening to this during X-Mas. So yes, BP does interfere with my family life in the sense that I get insulted and don't want anything to do with them. But also, sometimes when I get depressed, my parents give me a hard time and tell me to "stop sleeping so much".

I'm in the process of moving out because I can't take it anymore
