Honestly, I'm amazed that you've been able to do any work. You are such a strong person.

Have you spoken with the doctor who did the surgery? It might be a good idea to get your back checked out. The chronic pain support group sounds good.

Did the doctor who treated the Guillain Barré Syndrome give you any idea about what to expect? Hopefully s/he is doing follow-up appointments with you.

Hopefully you'll get your mojo back soon!
