I just know that ,i am a Muslim gay .What should i do ?

Unfortunately, you gotta tell the family if you want to move on. First, start by sharing with your most trusted sibling (best friend if you don't have a sibling) then ask your mother and father how'd they'd feel if you were homosexual. Treat it tenderly. You don't want to rip the family apart. That said, if they don't accept you, you should examine yourself and make a choice, hide your sexuality or leave them and go your own way.

Learn how vile Islam is and then do your best to help others leave that fascist ideology

Ask Allah for guidance. He alone knows what is in your heart.

Nothing

Pray the faith away.
