Im sorry you have to go through this so young. At 19 you should be more carefree. But your not alone. Millions of people have this affliction for various reasons, and hating yourself is a useless emotion. Hindsight is always 20/20. You were not to know, and who's to say that even if you took better care of yourself it wouldn't have happened anyways.

There are meds and supplements to help ease the symptoms and one that has worked for me is ALA. read up on it by googling it with neuropathy as your key words. Speak to your Doctor about it before you take it. It has lessened my affliction by at least 60-70 percent. I think you are in pain now and feeling hopeless, but there is hope. Be strong if you can and get a support system going.
