Being trans as a teenager

Being a trans guy while still being a teenager sucks, I don't have supportive parents (which is why I haven't told them I'm trans) and I don't feel comfortable telling my irl friends either bc they could tell my parents. I also have to keep hearing my dead name everywhere and I have the strong urge to yell "My name's not [dead name], it's Milo!!!!". I think that if I had a supportive family, then my life would be 10x easier,,, but while I'm stuck being a girl it's real shitty
