Ok, and I realize that you said you have been trying going out for nice walks, and it doesn't help.

Well, it depends on how long you are out, who you can interact with. And it takes time to get better (like a month or so). You have to have a high level of activity over a long enough amount of time.

And at least this: maybe the lack of stimulation is only part of what's causing your depression. Maybe there are several other factors as well. But if you are sure to be around people enough, and get enough exercise outside, and force yourself laugh while you are outside, (and perhaps some things other people suggested like listening to music and getting a pet, having enough water) over a month or two, then you can be sure that you've eliminated some of the definate possible causes. Then you can figure out and focus on other possible factors. For instance, maybe there's something in your diet, or maybe you've got a leaky intestine or something else.
