I am a girl and I truly believe I am 100% lesbian

I am a Christian and I go to church. I go to a Christian school and my parents are Christians. My life is basically surrounded by Christians who I know will not accept me for who I am because of this stupid thing they call sin. I can't tell anyone because I know they will think I am going through a phase. I don't want to lose my friends or my family.<br><br>Edit: I was expecting a lot of hate but I got none, thank you for being such accepting people.
