Aiko firstly I'm sorry you were struck with overwhelmingly bad medical news. If you can't stop after the appointment, then you HAVE to get outside help with this. Yes the body and nervous system are capable of healing themselves BUT, there is an expiration date and a point of no return. It's sounds a bit like alcohol neuropathy.
Right now you have the power to change your future. Do you want to live? Or do you want to drink? The second route offers irreversible nerve and brain damage beyond repair, strokes, loss of mobility, speech, job, family, friends, home and LIFE!!!
Please take your holiday time to get well!! You only get so many chances! Let this be yours!
