Hello Alexicat,
Welcome to the NeuroTalk Support Groups!

You certainly have been dealing with a lot and I'm sure you will be able to find information and support here.

You may have found your way around already, but I'll post specific forums below that may be helpful for you.
I'm not sure if your spondyloarthropathy is an autoimmune disorder or not, so I posted that link just in case.
I wish you all the best and I hope you're able to get those pain meds sorted out so that you can feel better fast.

Bipolar Disorder Forum

PTSD Forum
There is also a PTSD sub-forum at PsychCentral.
The link is in the PTSD Forum here.

Spinal Disorders and Back Pain Forum

There are also forums for Chronic Pain, Medications and Treatments, Social Security Disability.
The best thing is to just have a look at the list.

take care there.
