Managing anger

Seriously, my temper is giving me a lot of trouble, I really hope that i can curb it but seems that I can never do it. Why do I lose my temper so easily? Are there any ways that I can try to use it to curb it? Maybe I should go for courses/psychiatrist for anger management, or else, this will be the obstacle obstructing me from moving on. What my brother(BangZheng) said to me is quite true: you can't always put you unhappiness in your heart, even if you don't show it, psychologically it's still in there and will be obstructing you.
Talking about changing it is so simple but to actually doing it is damn hard, I was thinking true the whole night(that's why I haven't sleep yet), do people have more negative comments or positive ones toward me? Although some people say that: it's you life, why should you care about how people think about you, sometimes in life you still need to listen a bit(advices) from people, because what they said might be true but just that you didn't realize at all. I think that will be all for tonight, need to sleep, else can't wake up tomorrow morning for breakfast.
