Hi Jellibeans and Pyneapple! Thanks for your replies.
Things are going OK. I'm so stressed, I'm a big woman, walking on eggshells is not easy!

I didn't tell DD she passed the IT/RT (insurance approval) for residential, I don't want her behavior affected. I want to see if she truly is making changes. She almost doesn't seem like herself. She is not freaking out when I say NO, and it's really weird. She freaked out a little bit over chores though. I'm trying to figure things out, it's hard to explain. Before, there was always an explosion, so I expect it and I'm ready to cringe, I'm bracing myself for it, and then it doesn't come and I'm like "huh?" I don't know how long she can maintain pretending to be someone else.
She is taking her meds for me. They started her on Lithium to reduce sucidality 300mg twice a day and she got tremors, so it was reduced to once a day and the tremors went away. The P said that is a really low dose to get tremors at, and they may try increasing her dose again to see what happens.
So I just posted on another thread about my RTC story, and it really has me thinking. We have been tossing this around for almost a year! And writing it down like that, the pattern is glaring! We threaten RTC, she does better for a little while. I know it isn't a punishment or anything like that, it's just that we have tried every treatment available to us except RTC.
Pyneapple, you are right, this IS a whole family thing. We did in-home counseling with the whole family for a year. Right now I have my own T, she has her own T and DBT group and med management. My DD's biggest trigger is her friends. Drama with her friends. And she freely admits that.
Jellibeans, fear is driving part of my decision, I have SO much anxiety when she is home. I feel so responsible to keep her safe, and it is so hard to do, she is so smart and sneaky and manipulative. Right now we are watching for a couple weeks.
