Yay ! your insurance is back! I'm so sorry he broke his arm .. poor kid.. The main thing that I keep getting drawn back to is ... You both were treated kindly , this wasn't an out of control Bipolar issue, Of course there should not be any stigma and I wont even get into that BS, I think even tho he was hurt , he was seeing the ER and being treated well and maybe it help him heal from some of the past horrible trips in the past ..
I hope you both can get some rest.

Hugs hugs hugs to you both
