I'm apparently an interesting case when it comes to depression.
I HAVE been depressed in response to very emotional incidents, but all of my most recent bouts for the past few years have been physiological. (I was already physically depressed when the election happened, and it certainly didn't HELP the situation)
The first one that really stands out, was when I was bouncing back and forth between different locations and different climates on business, and for school. Texas, Alaska, Utah, Oregon, Taiwan, Mainland China, Japan.
By the time it was all over, I did not experience anything that really troubled me, that one would normally equate with depression. No breakups, no relatives dying, nothing. And I LOVE to travel and experience different places. At the end, I could barely get out of bed, I didn't want to do anything, I would turn on the TV, and then stare off into space while letting it run. I wasn't down in the dumps and thinking life wasn't worth livinng. I was just DEPRESSED.
The other one was more recent. I've been taking classes at a university in Taiwan, in Chinese political history, political science, and Chinese literature. I was born in Taiwan to a Taiwanese mother and an American (Iowan) father.
Despite the usual grumbling about lack of real guns, airsoft is much more mainstream here, and it's much easier to arrange meets (small island) and I enjoy that a lot. I also really enjoy learning more about Chinese history in general, and political science from the view of a culture that's so many times older and more experienced than that of the USA puts a very different spin on things.
I did that for two years, essentially without a break. I had used to toss on the hydration pack I bought for airsoft (a BlackHawk Hydrastorm Force-5 in desert tan), filled with textbooks and its full 3-liter hydration pouch, sling a huge laptop case (a 10 pound Dell M1710, bought when it was the state of the art gaming laptop) over my shoulder, and walk two miles from my apartment, to the campus, then walk two miles back after class. I was exercising, but I was eating too. I wasn't out to lose weight, and my weight stayed pretty stable for a good long while.
At around August this year, I started taking the bus to campus more and more often. I worked out less and less until I essentially stopped completely (one time every two weeks, more or less). Between the beginning of August, and the beginning of November, I had lost 50(!) pounds.
I'd stopped going to airsoft meets, started playing more single player games than multiplayer at home. Was sleeping almost 11 hours a day, sometimes more.
I hadn't been doing anything I didn't WANT to do for those two years, but in the end I still got depressed. And then the election happened, which REALLY REALLY made things worse. I decided I needed a break from all this, and came back to the USA.
