Hi and welcome to NeuroTalk Robin! Glad you decided to join us.
I had to do some research on the net to find out that CRPS is another name for RSD (Reflex Sympathetic Dystrophy). So...I learned something today!!
I have included the link to the RSD forum in case you haven't had an opportunity to visit there yet.

It's natural and very normal to be mad at a condition that limits you - especially if you were used to being very active....and it sounds like you were.
There are lots of very caring and wonderful people here at NT and I'm sure there are some folks who are very knowledgeable and can answer your questions relating to this condition.
