I think this is exactly one of the problems with modern society : we don't recognize the difference. Feeling blue and depressed is a natural state that everyone gets into occasionally. But actual depression is a clinical condition where the symptoms last for an extremely long time, at least six months. In clinical depression, the misery doesn't alleviate no matter how good life gets; thus, it is a problem with psychology and brain chemistry, not one of just "feeling blue".
Exactly.
I started being depressed when I was fifteen, got diagnosed when I was sixteen, and it was bona fide clinical depression. There is no way on God's green earth that that was a normal emotional reaction to anything. I spent up to nine months at a time incapable of being happy, was horribly miserable, started to hurt myself, oh and don't forget the self esteem.
What people keep forgetting is that one of the /other/ key elements of clinical depression is low self esteem. I don't know why, because that was by far the worst for me. I spent /years/ convinced that I was worth about as much as a cockroach, that everyone would be so much better off if I'd never been born, that all of my friends secretly hated me - obviously, because I was such a horrible person no one could possibly like me - and was pathetically grateful for them for having the saintlike ability to hide their disgust and put up with me anyway... frankly, I think calling clinical depression a "mental illness" is
exactly accurate, because I look back on the person that I was then and frankly? I was insane. Those were not normal thought processes.
I actually like to stress the "illness" bit because it is such an important distinction. Feeling down and sad after something happens to you is perfectly normal and valid and not an illness at all. But clinical depression
is not feeling upset after your boyfriend dumped you, or down because you have no friends, or whatever. (In fact, I wouldn't even say that depression is feeling sad, per se; I spent a lot of time /not/ miserable. I just didn't spend any of it happy. It was as if my emotions were capped somewhere in the "indifferent" range, meaning that during events where I should have been ecstatic I wound up more "meh"; I even recall no longer being able to remember what feeling happy /was/.) Clinical depression is an /abnormal/ emotional reaction and is a genuine illness.
