Oh Tink!! ((((hugs)))
I just read your entire thread. I so, so feel for you!! I think everything you are feeling is perfectly normal!!! Who could be expected to remain cheerful all the time going through what you have (and continue) to go through. People mean well when they say the things that drive us all crazy, but until they have been through it, they just can't understand! Of COURSE it is bad for you! Don't ever doubt yourself, you are incredibly strong!!! You are getting through it, your way. The only thing to hold on to is that you WILL get through it. It doesn't feel like it right now I'm sure, but you will get there. The fact that you have already increased your ROM so much is a testatment to that!
Take care of yourself, and please as you said to me, keep us updated on how you are doing!!!
