It sounds like a very negative n unhealthy atmosphere for you to be in. I won't go as far as to say its abusive but it is very unhealthy for you. I don't see anything improving until n unless you are removed from thst atmosphere unless you see some way they may treat you better? Would telling them your probs make it better or worse?

You may just need to go to a shelter so you can save for a place of your own.
