Family Complications

I hate being at my moms house, she calls me her bitch and makes me clean and do everything, Gabe (step dad) is a total perv, only really close to my dad but i don't want to come out to him cuz mostly of my sister. She's pansexual and my dad's house doesn't really tolerate her for a number of other things and receently i've been taking some of her clothes and liking them so i'm afraid of losing their support. I don't even want to tell my sister cuz i made a vow to not be like her but being lesbian, and my style kinda, is scaring me.
