<human>: I used to be in pretty decent shape in undergrad but in my senior year I had an accident that shattered my right arm leaving me with limited range of motion in my elbow and wrist. That brought on some other medical complications which knocked me out of the game for about a year and a half, and then graduating and not finding a job knocked the wind outta me and I just kept packing on the lbs. 

I'm finally committing myself to getting me act together, and I'm wondering if any of you have had experiences getting back into the game after a major injury/injury that affected your ability to do certain things (like lift weights, etc.). I'm really worried that it's going to affect me confidence that I'll be able to maintain this so I'm wondering if anyone else out there has experienced something similar, and what have they done?

Can you condense the text into a few key points?
