Thing's that make me sad: Cruelty, especially against children or animals, needless violence, anything like that.

Thing's that bug me: The smalliest thing's, the slowness of my internet browser, when my team losses a game, finding a video game tough to complete, stupid thing's like that.

You should alway's talk to people when your sad, i've started doing that recently and it helps a lot. Otherwise it will just all build up and you will get depressed and withdrawn. :)
