I want come Out.

Hello my name's Pietro I have 15y I discover myself trans when I was 11y but this only 3 years. I discovered at 02/06/21, and all this days I feel so much happy beginning a boy, but recently I just don't want beginning this secret bro, sorry for bad english, I cried all night think if my mom accepted me I have my boyfriend and my mother-in-law, they know I'm trans and accept me but my mom? Actually idk she say she would kill me if I'm "lesbian" I'm crying right now because I can't hide it for too much time this is killing me bro lol 😭👍
