Mother, tu gave birth to a devil-worshiping bisexual child. It's not anything that tu did nor is it your fault. I choose to be this way. If tu cannot accept that then tu should have reconsidered giving birth to me in the first place, only tu can't. There is no way tu could've known. I'm sorry it has to be me, I'm sorry if this is awkward for tu and I am sorry if tu just can't bring yourself to accept that. BUT I will not apologize for who I am. All I can do is ask for the woman who gave me life to accept me for who I am. I amor tu mom and regardless of your answer I always will, know that.
Actually i'd take it very carefully. If you're still a child (by legal rights) and still at home, then i think tu should leave it until you've made your own way in the world, with your own home, you're own job and tu know tu won't loose your home. If tu tell your mother now (if you're still living at home) then she may react badly and kick tu out and do tu have anywhere else to go? What about school? How will tu continue with your education if you're homeless? if tu tell your mother now and she allows tu to stay on at home, will tu be able to deal with all the pressure it's undoubtedly going to cause?
When and if tu are a ready to tell her, i'd sit her down, make a cup of té and gently explain that tu amor her, tu always have and always will but tu have made up your mind that the religion tu chose is the right one for you. That your sexuality isn't up for questioning and it's what tu are and who tu wish to be. And if all that fails and tu are definitely sure tu have somewhere to go and don't mind if your mother never talks to tu again, tu could say God made tu the way tu are, in His own image etc. But i'd take it very slowly, very seriously and only once tu know tu are going to be safe.
Well I mean she can't judge tu , Youre you. If she doesnt like it then oh well just tell her tu will continue to be who tu are. I'm bi and my mom knoes and she accepts that Buht I mean If tu wanna tell her lightly tell her thru text.
Walk up to her, stand two inches from her face. and say with just a hint of anger in your voice, say this: "Mother, I am a bisexual devil-worshipper, and I AM PROUD!" Slap her on the cheek, and walk away. tu also might wanna lock yourself in your room.
