Nick:
I totally agree with everyone else here... you need to see a doctor immediately. I'd call the endo back and see if you can't get in sooner.
Remember, neuropathy can be reversed if it's treated properly and aggressively. YMMV (Your Mileage May Vary). You definitely need to halt the alcohol intake, and try to get physical. Even if you have problems standing, there are exercises you can do to help strengthen your legs. Make sure to work with your doctor on a plan that will work for you.
In the mean time, we are here for you.
