Withdrawal, detox, and neuropathy

So, it's been about a months since I've stopped smoking tobacco.  The initial withdrawal wasn't as bad as I had anticipated, but I'm experiencing serious other physical symptoms that may (or, may not) be related.

I broke my back and herniated a couple of disks about 19 years ago, and I'm almost unable to stand, walk, sit, sleep, etc.  I'm also experiencing peripheral neuropathy that begins in hip joints and shoulders.  Throughout the night, I'm in constant pain and a state of anxiety. 

I've been diagnosed with RA, psoriatic arthritis, PSTD, anxiety disorder, severe depression, migraine headaches, ocular migraines, and a host of other medical and behavioral issues. 

Um................okay.  I'm REALLY tired of this - the inability to sleep, walk, sit, etc., has gotten way out of control, now.  When I finally decided to get up, this morning, both of my arms were tingling and numb and I attributed this to sleeping on my arms in some restrictive way.  Well, it's been 6 hours, and my left-hand thumb is still tingling. 

There are just some days when waking up is dreadful.
