I understand the anger, I'm an abuse survivor as well and I've been angered enough times that I cuss in my head all the time even though I actually hate cussing (sometimes I do it out loud, too, but only when I have the space to do so). What your parents are doing to you makes me mad, what sick people to try and hold power over you rather than be the kind of authority figures to help and guide you. I'm sorry you feel like you have to hide yourself around them just to survive.
Feel free to DM me too if you want to, you can vent all you want there.

It really sucks that there's people out there who get pleasure in hurting others and having power over them. They end up hurting some really sweet people. I just hate to see it. I wish all abusers could just go live on an island together and all the wholesome/normal people can be free to live their lives.
