I finally had the courage to tell my brother. I couldn't believe his answer. "You waited all this time to tell?" he said in a way he has always been expecting and says he admires how I have the courage to go through what I went, basically completely alone, and that he gets it now - my parents don't accept and my mom is basically blackmailing me and using it against me, mentioning my little dirty secret in arguments but not telling what it is. He said he wanted to punch her in the face. He said it's people like me who have to make the hardest choices and that he admires me. I'm so YAY I COULDN'T ASK FOR A BETTER BROTHER. I LOVE HIM.
