I too can no longer work and went through the 5 year fight with social security. I loved my job as the marketing director at a casino, the pay was good, and who wouldnt love giving away cash, cars, houses, trips etc.
After getting hurt and realizing the pain wasnt going away I continued to work even through the pain. But about a year and half later the casino was forcing me out because they said my job performance was low, and getting lower. So I got a job at another casino....what a fiasco that was. That is when it became apparent to me that work was something I was only gonna dream of doing ever again.
Believe me nobody would quit a job that pays very well, and has perks up the wazoo to chase the measly amount you get from SSDI. Although that was what the first judge said I was doing!!!???
You are on the right track, and finding something to do to distract you from the pain and limitations is the best thing you could do. For me it is computers, I love to build them and fix them, and surf the net, play games, and visit my friends in the forums
