My best friend has changed a lot since when I first became friends with him. He's 14. He's started to become so pessimistic about everything. Pretty much every conversation that we have ends up with him talking about death, and everything not being worth it, and that death will cause someone some sort of problem sooner or later, so you better get it over and done with.
Since we came back after the Xmas holidays, I always see him sleeping in class and he never used to do this, he always used to care. His grades have dropped by 40% I was so shocked, he used to get in the 90s and now he's getting like 53 - 58%.
Today when I came into school at about 7:30, I noticed him in the geography classroom by himself walking around in circles. The light was off and the room was pretty dark. I'm just so worried about him, and I know that you won't really be able to tell by this, but do you think he has depression?
