Hey,

I have been 'depressed' for many years, and I don't believe in the chemical imbalance.

I am not really sure why people get depressed either, apart from the serentonin issue, I do feel like I am hiding away and get easily put off things. It is like my resilliance has gone, so you are not alone and I think you'll find many others are feeling the same way hope this helps or puts your mind at rest a teeny bit.
