I have to take anti-depressants, and while there's a part of me that hates being tied to them, a larger part of me is happy that I can actually function on a day to day basis. Without the meds, I was a wreck, and as such couldn't think about larger issues like my personal eco philosophy. Now that I'm on them I can pay attention to recycling, growing my own plants/veg, focusing on environmental issues, etc.
Sometimes the bad is outweighed by the good. *shrugs*
