Claire,
I do see your point of view, but medication do help and some people (like me) can't live without it. Some of the doctors I've seen told me the first try of meds only works for 30% of the patients. The other 40% need an adjustment and the last 30% don't ever get them to work. It's really hard to find out when you're dealing with the brain, there's no such thing as a precise test to find out if and what meds one needs. Other than that, I've done all sorts of physical (especially blood) tests to check on me and I get tested every month to measure the lithium level in my blood.
I do see a therapist, I do exercise, I do take vitamins, but still my life is a mess if the meds aren't part of it. In the beginning, it was a major struggle to accept this as fact, but now I can feel the difference (and I'm not talking about fake happiness feelings provided by stuff like prozac - doesn't work well for me).
Without the meds, I don't go out, I panic, I cry, I feel a terrible void, I feel like death is friendly and life is nule.
But that's me! I have clearly a chemical unbalance. If your depression is caused only by stress of living and its consequences, you certainly can work it out, if focused on that.
Plus, I agree with you with the birth control thing. I've tried so many and now I REFUSE to take anything hormonal to deal with my PMS, cramps and birth control itself.
I hope I haven't offended anyone either.
