Oh my. I am getting this too. I feel exhausted and like I am getting sick, but I know I have been very stressed out, overwhelmed, not properly taking care of myself, and recently had a panic attack with a mild depression following it (and I haven't had one of those in a LONG time). So I have been having that flu/sick like feeling and it is really freaking me out - making me think there is some crazy thing wrong with my body. So I am glad I am not alone in this. I will say, I have been noticing the feelings more when I am home and when I am driving. A few times I have been out and about and don't really notice it. Then I come home or am stuck in my head while driving and totally feel it. I guess I associate it with being home - or all the work and things I have to deal with here. My rational self will say that that is a sign of anxiety - that it comes and goes. The flu doesn't until it completely passes. Does your symptoms, or feelings, come and go?
