Yeah, these two. Raiku (with light hair) is female, Velmu (the black one) is male. But he is castrated - so there won't be foals. Which kind of a suits me, as otherwise I'd soon run out of resources =) But maybe in the future, if I ever have more land.

Hey, telling a teacher sounds like a good idea! I don't know how they think, but I won't be surprised if some adults try to say that it is all normal - just emotional turbulence which is a part of your age. In that case, I'd advise not to believe them; ask them that sure it won't hurt if you get some more detailed examination. As, all the mental problems are easier to solve the earlier they get diagnosed. So, the thing you could ask is a possiblity to see a professional who could evaluate your situation and your need of further assistance.

Yup, extreme lack of energy was one central symptom of my years of heavier depression. There were days I couldn't get out of the bed. Sometimes I just cried for half a day. Most of the time I felt nothing. Sometimes I got annoyed and furios for apparently no reason at all. Things like that, and occasional problems with concentration and memory. And a lot of problems with social relations. And my social problems were fuelling my depression, making me feel even more isolated and worthless.

Just out of curiosity, as I was writing this, I took a self-test for depression, and answered the questions as I would have answered them seven or eight years ago. And this is what I got:
Major Depression: High
Dysthymia: Extremely High
Bipolar Disorder: Very Slight
Cyclothymia: Very Slight
Seasonal Affective Disorder: High
Postpartum Depression: N/A
