This is for coming out to your parents. I would suggest doing something where you can prepare for a reaction. Like a letter. If they say you're too young, try to counter it if you feel brave enough. Such as "well when will I be old enough for anything" or "if I'm old enough to know about [insert thing like puberty or how to stay safe when something dangerous is happening] then how am I not old enough to be lgbtq+" Only come out when you're ready. If your parents aren't supportive, come out to them at a time when you can cut all contact with them and have a safe place to stay. Come out to your friends first. If they really are your friends, they'll support you, and this will help in case you need to cut contact with your family. This is just a way to safely come out that I think should work.
