One thing that everyone must realize when dealing with PCS people is that this could end tomorrow, but it could be years and years until this is gone. For me, I kept doing stupid stuff because I was feeling better and thought that it was almost gone and thought that it would go away soon. It wasn't until I started doing a lot of private research that I found that I needed to get ready for the long haul.
Surprisingly this knowledge helped me to become more at peace with my PCS. Now, I do admit my parents and friends still have trouble accepting that I have almost constant pain, but I try to play it down for them, because they don't realize that although this is tough it is the way it is. I have an easier time with it than they because they are struggling with a horrible idea while dealing with the reality is somewhat easier...I know exactly how much pain I am in and I know exactly what will hurt me more and what will hurt me less.
I don't know if I am making sense because today is a very bad day...Oh, well such is life.
Good luck!
