What are my benefits after getting chaptered for overweight?

I was injured in Iraq and was left unable to run/walk. I was pushed to the side (army medical) untill i got to my new unit. i have been on a profile for over a year and a half and i have been unable to do any kind of PT due to my injury. now i am seriously overweight and pending a chapter. I know its my duty to be in shape and blaa blaa blaa. i know i dont belong in the military any more because i am a fat dirt bag but i was just wondering what kind of benefits i might still be able to get when i get out. i dont have a purple heart or anything but the hospital and my unit is aware that i was hurt in iraq but they still want to chapter me. any help would be great
