Complete betrayal

okay, just a quick disclaimer, i have never used a forum before, i know im really new here, but im hoping that isnt an issue, so just bear with me. I am a 14 year old, lesbian, pagan. I was raised in a home of strict baptist christianity, with straight patriarchal parents, and a 16 year old sister with perfect grades and a perfect boyfriend. my parents and i have never been very close, and so, as ive grown up i have come to know lying quite well, despite this ive always hated lying, i want people to know me for me not for the supposed boy loving me or christ loving me. a few months back my mother found out i was pagan, and immediately accused me of devil worship, we stopped speaking for about 2 weeks. We finally spoke again and she forgave me for my "wrong doings". and so i went on with life, and 2 months later i came out as lesbian to my sister, and to my surprise she was completely okay, then come to find out she is bisexual. She tells me it is a horrible idea to come out to my parents, she says she doesn't want me to get kicked out and disowned, and she says "besides, this way you can tell them your girlfriends are 'just friends' and they will be able to spend the night and everything". her point sounds so appealing, and i know its the easy way out, but i cant keep lying to my everyone.. all i can think though is that they will see this as complete and utter betrayal, first im pagan, and now gay too?? i dont know, i need help guys.. i still want to be able to have girls over, my best friend for 5 years is a girl.. what if they think i love her and never let me see her again?? i want to be free, but im too scared that i will become even more incarcerated by this so called "freedom" of leaving the closet.. please help.. thanks.
