All the same, if you feel lame for months and months, seriously consider getting on something. Personally I think a lot of people can survive a brief downswing, but a lot of others can't. Stressful events often do trigger depression in people, and some of us don't respond well to it for some reason or another.

Depression doesn't always lead to great ideas or clarity of thought. I think often there is this thought that we should be able to have a Zen-like control of our brain and will ourselves to have more serotonin or norephinephrine or something. We feel like we should have some brilliant ideas that we are the people who see the dark side of life and so on. But often it just leads to thinking that those thoughts all suck and that you don't have anything worthwhile to do and what's worse, you don't bother trying to do new things, find new interests. At least that has been true for me. I think we all have our ups and downs, but some of us don't get those brief downs that aren't so bad. Some of us actually stay down for a long time, and it is not healthy or fun.

Anti-depressants do not turn you to some placid stable person who never feels anything. You still have ups and downs - you are just more sane, is all, and better able to bounce back from things . Anyway I just wanted to offer another perspective...
