Anger and sadness

I'm trying SO hard to stick to my 2nd New Year Resolution. Just that its easier said than done. Don't laugh at me, but heres one reason which I became extremely depressed during Science class. My friend was sitting with my crush. WTF. I don't even know why I should be sad about. What is wrong with me?! Then after the depression I got so dizzy I felt like fainting....

Another way how I got angry. I was playing MW3 on my computer when the screen froze halfway when I was playing. I'm not even gonna tell you what I did.

Its so hard. I think I'm gonna die. Help.
