You definitely sound depressed. I like to think of happiness as something I'm either taking in or using up (like food). Starving people can't immediately eat large meals. I would think of your condition in the same way, except you're starving for energy/life/happiness. You can build it up though. Find a little bit at a time until you can use that to find more. Find something (anything) that holds your interest. So you can try to build up interest to eventual happiness. It will probably require social interaction. It would be great if you could eventually talk about a passion you have with someone who shares it. I'm an intellectual introvert and a social animal. But if I'm in my house for weeks learning stuff, I start to lose my social appetite (meaning I don't want to talk to or meet people). Forcing yourself to do things feels meaningless, but it isn't always. You can find enjoyable times on accident. It's not always possible to predict whether you'll have a good time, so you have to use your energy to at least try. I gave this advice to a friend and it worked. She started taking photography classes and I helped her figure out why she was depressed (moved home, no job, fewer friends, etc). Good luck.
