I was just wondering how people would describe the way they feel when dealing with depression. The reason I ask is, for me depression seems purely to be the way my head feels... that is there are times when my head feels calm, at peace, and it feels as though life is ok, despite problems, there are plenty of days ahead to achieve things I want. Then, my head can feel different other days, as though it's under pressure, even when nothing major has changed, there's no more thinking of years ahead, but just today and possibly the next few days ahead. Suddeny; suicide, which was never on my mind previously is one of the main things I spend the day thinking about. I was on medication for a while, and during that time did not think about suicide much at all, and when I did, it was in a different way to when I spend days on end thinking about it. That's why I'm currently buying in to the chemical imbalance theory, but how would you describe the changes you go through, from when you were happy to when you're depressed?
