Hey! All is NOT lost here...
A number of meds for depression also help with neuropathy by decreasing pain receptors, and you can decrease any more problems developing with diet and good blood sugar control.
Have you seen an endocrenologist and/or diabetes specialist and maybe more importantly a nutritionist/dietician familiar with diabetes who can help you find a food regimen best for you? If not, please try it... c'mon, the worst thing that could happen is that it doesn't help, but I really doubt that, and regardless, if you're feeling bad now, why not seek out someone that can possibly help...
Our most basic functions include eating, so why not see someone who might be able to help you find a way of eating that can help you? And as diabetics, what we eat is really important and can have a surprisingly amazing impact on our blood sugars, health, energy levels, and emotional states.
If pain is the main issue for you, please ask for and/or seek out a pain specialist; there are so many amazing and low-risk treatment meds and therapies available now...
Best to you...
All is not lost. Hang in there.
In regards to your Neuropathy. In 99% of the cases it is not reversable. Sometimes if Neuropathy comes on very fast and it is treated aggressively very quickly it can be reversed. Otherwise, chances are very slim that it can be reversed. HOWEVER, it can be treated quite effectively with drugs that will help the pain and other problems so all is not lost and keep going to the Dr. to get it treated properly. I am not a professional but I had a really bad case of Neuropathy that was treated and controlled and then eventually reversed to complete recovery so I know it is possible.
