I also suggest you get into some type of therapy, you're probably depressed, and that was one of the first tell tale signs when i first got sick. I did't feel like brushing my teeth, but also couldn't take care of myself right. not showering is bad, but it can make you feel alot better once you actulally take the shower. I say take a shower and brush your teeth after the shower, you be so glad you did, washing off dead skin that builds up on our systems is a great way to stay healthy too.
