Do sufferers of CFS share personality traits?

My GP explained to me that I need to do everything to 80% capacity from now on, which has been interesting as I’ve realised how hard that is for me to do. It seems my default has always been to do everything at 120% capacity. Prior to CFS I always overdelivered and had super high expectations of myself (although I didn’t necessarily see it that way, but other people frequently commented on how hard I am on myself). Since CFS, learning to not push myself past my limits whenever I regain a little energy has been quite challenging so far.

I’m curious if others here also share this tendency?
