injured and trying to stay motivated

Long story .... I fell off of a platform and severely sprained my right ankle (IN SEPTEMBER) and have been living in a cam-boot. I tore one ligament, partially tore 2 other ligaments and am getting tendinitis. After 3 months of restrictions in weight-baring activities, walking and stretching I was finally off to physical therapy. I began walking again (elliptical machine), stretching and some abdominal workouts.

I had lost 20 lbs .... and then went back to the doctor only to find there has been no improvement and was placed on harsher restrictions and put back in the cam-boot. Now it's been 4 weeks and I've gained 4 lbs back. I'm lacking in motivation and am so sick of just doing weights/medicine balls and rubber-bands.

I don't have anyone to help motivate my weight-loss but me. I'm finally getting back on track and I need help. I'm mentally in a better place now and I'm getting myself back on track. I need ideas for what I can do to promote better weight-loss until I finally heal. Can anyone give me some suggestions?

Restrictions:
*weight-baring activity
*squatting
*cannot remove cam-boot
