First goal: become happy enough that I no longer have trouble recognizing people.
I've never had that happen, and I've dealt with a lot of depression. Sounds more like a nervous breakdown to me. But! If it's really depression, I'd recommend three things: 1) Watch a movie with friends each weekend (or other mutually fun activity), even if you think you don't have time for it. Make sure to smile, even if you don't feel like it. 2) Eat healthy, regular-sized meals. Even if you're not hungry. 3) Exercise! Make sure that's a priority.
Of course, listen to your shrink over me! Just make sure you start getting better.

Complaining time: So, there's this girl I know. I knew her in sophomore year, and we mutually crushed on each other. Thing is, she was pretty messed up, and I knew that a relationship would have hurt us both a whole lot--I've seen this go down too many times. So I deliberately friend-zoned myself to save the trouble, and decided that if I really did like her, I'd do my damnedest to help her through her problems.
It's now Senior year for me, and, as far as I can tell, she's made a crapton of progress. I'm going to go ahead and say that I was a big part in that, though she might disagree. Right now, I'm tutoring her in her physics class.
After one of these tutoring sessions, I dropped her off at her dorm. Right after she left, the question popped into my head, "Was it worth it?" Giving up on a relationship to help her out of the shit she was going through? I know it was the right choice. But we've had this UST floating between us all this time, even though I'm in the friend zone. And since I've met her, I've not been in any sort of relationship. And it's the spring.
So I should give this question a crushingly loud "Yes, it was worth it to see her break through all the muck," but I can't. Hell, I'm a few minutes away from saying, "No, I'd rather have made out with her." And I feel like a royal jackass for it.
But! Bunnies exist. Therefore, not everything's bad.
