Why dose my homeostasis have to be sick?

It seems unfair to me that I mostly spend my time being ill. Not really ill. Not the kind of ill that you can point at and say yeah I'm sick see? I have blue knees.

No. I'm just under par. My head hurts. My stomach is queasy. My muscles are kind of achy. I want to curl up in bed and not really move. But I've done that and it doesn't really help. This illness comes and gos but, it seems like there's generally something that is wrong. If I'm happy I can usually just ignore it and pay attention to something else. Which is nice. But when I'm down its very hard to ignore the headache, the queasiness, and the general feeling of wrongness that pervades my body. Its at times like these I wonder, am I making myself sick? Or is it the illness that makes me feel down?

Chicken or egg?
