Yes it is. Has been since early childhood, even though I could cover it up till I got to college. The worst part is that deep down you hate yourself for not being able to just snap out of it-I see it from everyone else's perspective as well as my own. It is the most complicated puzzle I have ever tried to solve...I think intelligence and self-awareness have alot to do with how people experience depression. Lots of people blame others, and trite life circumstances that they put themselves in without realizing it. I could go on forever about this, but Im fasting so I'd rather chill haha. The thing that keeps me going is that every now and then, actually quite regularly, I feel REALLY good for no reason. I revel in these times. I experiment with my thoughts when I'm on these "highs"... think of the really deep dark sad things that I usually associate with depression, and guess what? They dont bother me. I feel above them. This helps me believe that the root problem is physiological. Anyway,didnt meant to be short with you, theres no point in that.
