I know where you're coming from, certainly, but personally, it's a funny question, mainly because game development IS how I cope with stress. I don't wanna bitch too hard, but life was pretty shit the past few years, in and out of hospitals, institutions and the sort. Took me bloody ages to finally get to a fairly comfy state (and required me to cut down heavily on socializing since people really do bring out the worst in me), but no matter what happened, gamedev was always with me. I'd write character stories and such on my phone when I had no access to a PC, sketch in a notebook despite being absolutely crap at art - I'd do that to keep myself somewhat sane, was probably the only damn thing that remained stable as the whole bloody world was crumbling around me.
Even now that stuff's more calm, I still love getting lost in game development, because it's so easy. There's still a bloody million things I need to do, a new unique challenge for each day. The world is a depressing place when you think about it. Wars, daily riots, a political environment where everyone has to very loudly state their opinions or else both sides will hate them, a society that will make a villain out of you for completely arbitrary reasons… Companionship is not really possible to find anymore, not for me, at least. Thinking about all of it is bloody depressing, and you can't go on the internet anymore, anywhere, without being reminded of all that. But game development never leaves you, it doesn't give a fuck, it CAN'T give a fuck. It's such an open ended goal - "make a game" - that you can really do anything and still make progress.
I spent a week reworking and perfecting my existing soundtrack, but ran into a roadblock with one song. Got really sick of it, and saw people on the /agdg/ generals talking about blogs for progress and such. Figured I should make a website to host all my future projects, so I went into Tumblr (no shekels to host my own, sadly). Looking around, I realized that all the the themes were absolute shite, so I made my own, with next to no prior knowledge of HTML or CSS, in three or so days. It's fun, it's rewarding, and most of all, making good progress actually gives me a reason not to despise myself.
One game, one single project, can hold me over for probably up to three years. And once that's done? Just make another game. And another, and another. I don't do it for money (and I'm not even charging anything for at least the first few), I'm not doing it to push my own politics on someone like SanFran liberals love to do, the useless fucking subhuman pricks. No, I make games because it's the only hobby I have that I can truly get lost in, that truly makes life fun to life. And most of all, it's comfy.
Sage for what most likely turned out to be a really autistic blog post.
