Okay, depression sounds good. I used to think it was depression, since I didn't care about anything anymore and didn't find any fun in things I used to enjoy on a daily basis. (See? I'm reading the replies and I didn't leave my thread as a rant-thread! )

By the way, I forgot to add: I don't have triggers for my feelings. They're just there, all the time, every day. I distract myself half the time by listening to music, playing games, or socializing (right after distracting myself, so I listen to music to calm myself down, then I'm able to socialize normally). And, of course, there ARE triggers which increase the intensity of the feelings, but that's normal for every feeling, so yeah.
