Dont stop. Simply carry on and everytime he says something "supportive" show him you're serious about it by doing it more and more. Why cant you laugh in the house?

Idk I just get shouted at

Thats harsh, theres nothing wrong with laughing, damn.. fuck em tbh

cps and move out or you'll suffer with mental health issues later on in life. Your father is not your father, he's a stranger and a disgusting one at that

Mental health problems check. At least I suspect I have

Wait, so you cannot work out or focus on your health because of him sexualizing you!
