My dad calls me stupid and ugly and idk what to do anymore, i'v cried myself to bed every night?

I'm sorry to hear this. My dad used to tell me that the "men" were coming at the weekend to take me away and lock me up in a mental institution. When I got older, I realised he was projecting fears he had about his own mental health because he couldn't deal with it so he pushed it onto me. It's possible your dad is doing the same. I doubt you are stupid or ugly. Your father most likely has problems. Although it's difficult not to take this personally and it's awful being used as an emotional punchbag, try not to take his words as truth. They're most likely not.
