I didn't have a "big" one , but I had one while under the knife. Just keep after it and you will progress. The first couple of weeks after I came home were tough to say the least. If I had listened to my wife I'd still be walking to the mail box and back. You will know when you've gone to far. Learn what your body is telling you and your recovery will be as fast as your body and mind will allow it. Good luck. When you get feeling down just remember, what gun powder smells like.
Don't forget your friends they won't know you want them around unless you tell them.
