Phoenix,
It´s very hard to deal with pain, but no wonder if you´re depressed. On top of dealing with insurance and legal stuff you have a broken bone in three places. Jul´s advices are so good and effective I have little to add but my sympathies.
18 months ago I was in a car accident. An old man "forgot to brake" and rearended my car when I had stopped at red lights. He was on 80 km p/hour, and I got a nasty whiplash and displaces two discs in my vertibra. I was treated in a hospital and came out with a collar around my neck and couldn´t feel my hands and fingers for 10 days. I was depressed for weeks. I also started to do too much too soon.
This accident became a blessing in disguise. I sued the man´s insurance company and got a nice sum of money.
It takes time to build yourself up after an accident. I understand you had a motorcycle accident, not your fault. I advice you to sue.
I wish you the best of recovery, and try to rest as much as you can. Accept your present state of irritation, it goes with the accident, and it will pass.
