Come out as trans?

Andreas

I know that I'm trans (female to male to be specific) and I've talked to my friends about it. They're all really nice, accepting and loving and call me bu my preferred name and pronounce in our free time. I want to tell my family as well but every time I even think about it I get really anxious. I also have panic attack disorder and I think coming out to them and in school is going to be a bit to much, plus the stress I'm already under from grades and stuff. I honestly don't know what to do, any advice or pep talk?
