Please help

I’m 15, and I’ve been raised in a Christian home all of my life. I’ve been taught that homosexuality is a sin, yet we should still love homosexual people (hate the sin, not the sinner). I’m a girl and ive been attracted to other girls lately and identifying myself as bisexual to certain crowds. I know it’s wrong but I don’t know what to do about it. I’ve also been feeling EXTREMELY pressured to smoke and drink and I’m tempted to have sex as well. I feel like I have so much rebellion that I need to get out and my parents are super strict. I don’t know how to deal with it and I have absolutely no one to talk to. I need a Christian accountability partner. I feel like all of my what used to be Christian friends are also becoming atheists and I just desperately need help. If you’re interested in being my new internet friend message me please! And please just give me any tips or advice💕
