I go through tired phases that last a couple of months. Times where I will just be exhausted no matter what my mood is like and no matter how much sleep I get. At these times I start to wonder if I should get my blood checked for a deficiency of some sort...but I never do because I hate doctors. At most I'll throw in an iron supplement since I do tend to get anemic. And then it will go away and I'll be normal for awhile.

This has gone on for a very long time, at least seven years, if not longer. I've never figured out why but since I spent most if those years off meds I know it's not that.
