I'm not a medical doctor, so I won't give medical advice. Speak to your doctor.
However, I can give personal advice. I was here as well as other forums almost a year ago asking about drugs for my depression / anxiety / problems. It was a very severe depression with near constant thoughts of suicide. The posts were about 50/50 split over taking the drugs (this is only counting people who have taken them). I thought and thought, and eventually I decided not to take them.
Instead, I turned my life on its end. I analyzed everything about my life and attempted to improve it. Even if it meant pain. Even if I didn't want to do it. Even if I'm broke from it. I did it.
I dumped my problems. I dumped the things I liked but that prevented me from being truely happy (this was the hardest part, the temporary pain for the better good). And I can't be happier given my situation. Sure I still have some problems - but I see them as minor problems now. But my severe depression(s) is gone and I walk around with a smile on my face all day long.
I divorced my wife (the source of much of the depression), divorce was a temporary pain for the better good. I stopped playing computer games, another temporary pain for the better good. I socialize everyday instead of sitting at home wallowing in my depression. I've called up old friends. I've traveled and visited family. I found a wonderful new girlfriend. I've (slightly) changed my eating habits. I'm exercising and I really like the changes to my body (130 pound weakling became a 130 pound muscular guy, I just need to gain some weight now...)
Depression gone. No medicine. It can work. But still talk to your doctor. Good luck. There are those of us on Anandtech rooting for you.
