I hear you Lyn, and understand some of what you re going through. So Sorry..

It seems that all the PT & OT I'm doing is causing me some, bring to tears, pain in my right shoulder/rotator cuff. Either that or I'm sleeping wrong...etc? It's my good arm, so that makes it especially difficult.

It's much worse for you, since you are working. I don't know how you do it! I hope Doc can find out what's causing your pain and do something to stop it. That's why we pay them the big bucks.
