I sorry for your situation. In general tissue remodeling (the process where scar tissues/temporary fixes change/reorganize in order to recover from injury/become more permanent fixes) can take a long time (months to years). Generally being healthy, eating healthy, and being young is a great boon. If you use tobacoo products (smoking or dipping) now would be a great time to stop (no nicotine gum or e-cigs either). More and more evidence is showing that nicotine retards the healing process a great deal.
KMCNYC has already given you some great advice. You are under the supervision of therapists and doctors who should know what you should do. Try to follow their advice to the letter. Honest 100% compliance can really result in some good things. The caveat to this is that you need to trust your doctors and therapists in order to do this, and that trust needs to be appropriate. If, for whatever reason, you don't think your doctors or therapists know what they are talking about, then you owe it to yourself to find some that you do trust enough to do what they say.
This is all general advice and may or may not fit your exact case. I am just some jerkoff on the internet. Listen to your doctors. Best of luck.
