Hi Miriam! I'm new here too and certainly relate to your feelings of 'hopelessness' !
You sound exactly like me (but I'm 20 yrs older )

In some of my initial diagnostic workup, it was discovered that i had hyPOthyroid, which contributed to alot...so i figured once i got that under control with medications i'd be good to go. WRONG Neuropathy is the most mysterious and wicked curse I have ever known !
After 5 years and thousands of $$ worth of ruling out everything else, I have come to the conclusion that there IS no conclusion! To me, first and foremost has been hooking up with other people who understand and going thru the same battles......once you've hooked up and realize you are NOT alone, then comes the serious homework.....look on the websites that people share on this forum, read other people's stories of tribulation and triumph. TRY to have some semblance of humor....and hope......and eventually we WILL have our own story of triumph! i hope....

Please hang on to hope......
God Bless
