Thats pretty much it for everyone. At my school I was taught that almost no major depression comes soley from biological reasons or things happening in life. For me, I'm quite sure I have a chemical imbalance... but in my head... I just keep hearing "ACTUAL" reasons to why I am sad... the reason I so highely think it's combined with biological things is because I sometimes get very sad for very stupid things. I can know myself that it is nothing to be sad of be still I can't help it..

Simply put.. I don't know when a strong emotion occur if it's mainly due to something biological, to what my head tells me, or something else that goes on in my life.

Although I don't think anyone should have the approach of that they are gonna be on meds for their entire life when they get their hands on some.
