Can't say I can offer much advice, but I empathize with ya, Anon.
Father was a military man who "beat the fag out of me" a few good years ago, shit happens, and now he doesn't get visitation anymore. Mother however isn't all keen on it, went in complete denial when I refused to let her cut my hair and is now telling everyone the only reason it's growing is for Halloween.
She stole all my razors after I shaved my legs for the 1st time. So I sneak out while she's working and buy supplements with money I can't get from her. Once my cache went missing and I'm starting to genuinely believe she doesn't hold any memory of throwing them out. If resorted to theft at times and it's not a happy life but I have friends who support me and I don't know why I decided to share this all exactly, but I felt like giving a shout out to the few people who are helping me avoid a drug induced coma
