Yes, I can totally relate. I was diagnosed back in 1987 and after many years of struggling to work; I applied for Social Security in 2001 and was approved. While that's great for not having to go to work every day. Unfortunately, I still feel sick. I understand the running fevers, joint pain, fatigue, depression, etc. I am irritated with my rheumy and trying another one next week.
Try to hang in there and know that there will be better times ahead.
