D.D.
I had a friend who ended up with drop foot after being hospitalized for an extended amount of time (double lung transplant with complications). He did a lot of PT and wore a boot. The issue he had was that this wasn't even on the radar of treatment for several months so his outcome after everything was done was enough to be able to function but not much more.
Be your best advocate in your treatment. Ask as many questions as needed. Do your research. Work on PT at home and try to push yourself as much as you can. Although the doctors are there to help its really you who has to make sure you are getting everything you need. Become your own expert of this.
Its ok to be depressed over this because its something you didn't foresee or expect. But now that its been 6 weeks you need to stop the pity party and become a warrior to fight for what you want.
