Big_Bear - I hope you are not offended. I suggest that you visit the forum on this site that is dedicated to the issues of caregiving. You are not a caregiver, but people who are would be able to share their experiences and I am sure that there are people caring for SO's with autoimmune diseases. You would also get compassion and support on that forum, hearing from people who neglect meeting their own needs due to the pressures of caregiving. It would be an all-in-all good educational experience for you to browse that forum and maybe pop a question or two.

In RL, there might be support groups for MS sufferers and their SO's. That would be another, and possibly better, way to see how people deal with the challenges you are dealing with and will be dealing with much MORE if you stay with your gf. No offense, OK? I just wanted to say that MS is way worse than anxiety. I have anxiety and do not have MS and I am thankful - deeply thankful - for that. I would take anxiety over MS any time.
