I had a six week experience years ago. All I can say is this, focus on you, why YOU are there, what you can learn and gain, and don't get caught up in anyone else's drama. The staff isn't blind or dumb. They see who the trouble makers are, who is trying to move ahead and who is trying to hold everyone back. They see it. Haters are gonna hate, even though it's hard to ignore their drama, remind yourself that their issues are theirs, and stay focused on you.
Hugs, I know these living situations are not easy, and in the end, you might choose to find another situation, but wherever you go the basics are the same. You take care of you, and don't let others drag you into their games.
