Lately I've been feeling upset, depressed, angry, or some mixture of the three almost all of the time. I rarely ever cry usually, but now I cry all the time, sometimes at something stupid like not understanding something in physics class. Whenever I hear something sad, especially about other people's misfortune, I cry almost uncontrollably - for example at my school we had a group of children from Uganda visit us and tell us about their lives, and I literally couldn't stop crying for two hours. I just feel like the only real thing I've ever learned is that life is miserable and difficult everywhere and for everyone. I'm constantly reminded of this, whether it's in history class learning about child labor or just watching the fucking news. I feel unhappy all of the time, and everything I do makes me feel frustrated or upset. I've even thought about suicide; I haven't actually considered it but I've thought about it. I just don't know what to do anymore and I'd love any advice.
