Brokenfriend,
I am so sorry to hear about the troubles you are going through with your family as well as your own health
I went through something similar when I was diagnosed with CRPS/RSD - my grandparents and dad didn't understand, and still don't understand what CRPS is.
I just want you to know that you are in my thoughts and prayers and if you ever want to chat I am here for you
Best wishes
Alison
