Samana,
So sorry to hear all that. What kind of accident did you have if you don't mind?
Mine was a semi truck accident.
I know about loosing abilities. I used to play guitars and played bass in various bands in my youth. When I lost the use of my left hand I was emotionally crushed. My wife knew of my love for music so she bought me a keyboard so at least I could teach myself one handed.
I too am in a wheelchair. My RSD is spreading and I also had head trauma cerebral atrophy which effects my balance so I fall a lot.
The best thing is to try to focus on the positive things we can do. Don't let this disability beat us...
