Lately I haven't been able to control my tamper, I be broken my cupboard the light switch to my room and thrown my phone around, I did all this to avoid hitting someone else, but today I couldnt find anything to vent my anger out on and almost stabbed my friend, someone help please.

What exactly got you that mad in the first place, first of all?

I've been stressed out with school and work, there's a major exam this year, I haven't been able to get any sleep, and suddenly the smallest things get me mad like an argument over a dollar or something stupid like that

I know how you feel, I managed to no be so angry by not even talking with people that aanger, and if it's just an object or an action that pisses you off then just ignore it.

Also the past week I got sick and I didn't went to school for 4 days (6 counting with weekend) and that made me peacful again, it relaxed me so much that I could talk about thing that made no sense without hurting or yelling at anyone.

So my advice: get some days off, about a week from Sunday to Sunday, and don't go to your PC, don't play anything just stay in bed and sleep, eat when you're hungry and go to the bathroom when you feel like it.

yeah >>4 is right u should that
