Take Robert Wright’s class on the science of Buddhism, he teaches and discusses a lot of the skills that would help you in confronting your problems with anger. It’s free.

This is assuming you’re not dealing with problems as a result of past abuse or some other significant problem, if that’s the case then see a therapist.

One element of Buddhist beliefs is that there are different components to your thinking that make up your thoughts and feelings. One component will always suppress the others. So if you’re working on something difficult one day like a calculus problem and then you walk into a room that has a nice chocolate cake, the hunger part of your mind will suppress the part of your mind that wants to work on something challenging. Once you’ve finished with the cake then the working part of your mind can return.

For you the component that triggers anger is overactive. This means that it takes little stimulus for that part of your mind to take over and suppress the others. With practice you can learn to see the anger coming and ignore it and not react to it. Over time it will take more and more of a stimulus for anger to become dominant. But it does take practice.
