I just facepalmed again. Things like this frustrait me so much, I just wish there was something I could do to help. :( It's just not right! I cannot believe how well you taking this. I really can't. You must have some amazing strength.
I'm glad you're moving out soon. You need to get away from her, or she really needs to get some serious help. Because she honestly shouldn't be around you guys if she's that unstable. I hope she doesn't give you too hard a time during your wait to move.
