I Dont Know Why

For me it's either depression or just needing to take care of myself even when things are going well. And if you're feeling sad, maybe reassess how great things are really going. I'm thinking it might be worthwhile to spoil yourself a little bit. Go out to eat if you'd like, listen to your favorite music, get a massage, go to a concert, and other things that you might enjoy.

Darn it. So it isn't just me. Though mine is irregular. Flapping mood swings.

it could be a physical illness other than a chemical imbalance
