I have this problem to mostly when depressed. Even sometimes when Im manic, I will find that I have been so busy I have forgotten to shower. When I am depressed I do good to get one every other day or third day. But I never leave the couch so Im not exactly working up a sweat or getting dirty at all. My doctor says its very common in bipolar and in people with depression. Sometimes moving my eyes is just to much exertion when Im depressed so showers are out of the question. So congrats on the shower becasue to us thats a big accomplishment.
