Hello. Long time and I am sorry you have so much going on. I am sorry about your child and as someone who has been residential many times I know the stress this can cause on the whole family. I hope you all can do family therapy because I think it will help you and your child cope.If I can help on that front please pm me. I have experience in that front and really it can help your child so much. I used to have ocd so bad for ex my hands would blead from the washing and now I really don't have any ocd behaviors. It took time even after residential but it was a good starting place.
As for you pain I have sometimes where a fan blowing feels like a beating. Mine is similar to rsd they say and that is a symptom.Can you take a sleep med in combo with that med? I am sorry I don't have more to offer.
