In this world nothing can be limited between this parents and son relationship. I am sure after few days u must be repented for this time. Pl take it easy. its just for ur age.
Here are some Strategies that might be helpful to to keep anger at bay:
1. Relaxation : Simple relaxation tools, such as deep breathing and relaxing imagery, can help calm down angry feelings. Some simple steps you can try:
•    Breathe deeply, from your diaphragm; breathing from your chest won't relax you. Picture your breath coming up from your "gut."
•    Slowly repeat a calm word or phrase such as "relax," "take it easy." Repeat it to yourself while breathing deeply.
•    Use imagery; visualize a relaxing experience, from either your memory or your imagination.
•    Nonstrenuous, slow yoga-like exercises can relax your muscles and make you feel much calmer.
Practice these techniques daily. Learn to use them automatically when you're in a tense situation.
2. Cognitive Restructuring
Simply put, this means changing the way you think. Angry people tend to curse, swear, or speak in highly colorful terms that reflect their inner thoughts. When you're angry, your thinking can get very exaggerated and overly dramatic. Try replacing these thoughts with more rational ones. For instance, instead of telling yourself. Be careful of words like "never" or "always" when talking about yourself or someone else. Remind yourself that getting angry is not going to fix anything, that it won't make you feel better. Logic defeats anger, because anger, even when it's justified, can quickly become irrational. So use cold hard logic on yourself.Say,  "I would like" something is healthier than saying, "I demand" or "I must have" something. When you're unable to get what you want, you will experience the normal reactions—frustration, disappointment, hurt—but not anger. Some angry people use this anger as a way to avoid feeling hurt, but that doesn't mean the hurt goes away.
3. Problem Solving
Sometimes, our anger and frustration are caused by very real and inescapable problems in our lives. Not all anger is misplaced, and often it's a healthy, natural response to these difficulties. There is also a cultural belief that every problem has a solution, and it adds to our frustration to find out that this isn't always the case. The best attitude to bring to such a situation, then, is not to focus on finding the solution, but rather on how you handle and face the problem.
4. Better Communication
Angry people tend to jump to—and act on—conclusions, and some of those conclusions can be very inaccurate. The first thing to do if you're in a heated discussion is slow down and think through your responses. Don't say the first thing that comes into your head, but slow down and think carefully about what you want to say. At the same time, listen carefully to what the other person is saying and take your time before answering.
5. Using Humor
"Silly humor" can help defuse rage in a number of ways. For one thing, it can help you get a more balanced perspective. When you get angry and call someone a name or refer to them in some imaginative phrase, stop and picture what that word would literally look like. If you're at work and you think of a coworker as a "dirtbag" or a "single-cell life form," for example, picture a large bag full of dirt (or an amoeba) sitting at your colleague's desk, talking on the phone, going to meetings. Do this whenever a name comes into your head about another person. If you can, draw a picture of what the actual thing might look like. This will take a lot of the edge off your fury; and humor can always be relied on to help unknot a tense situation.
6. Changing Your Environment
Sometimes it's our immediate surroundings that give us cause for irritation and fury. Problems and responsibilities can weigh on you and make you feel angry at the "trap" you seem to have fallen into and all the people and things that form that trap.
Give yourself a break. Make sure you have some "personal time" scheduled for times of the day that you know are particularly stressful.
Good luck.

First, your anger is obviously very real, and if you father used to beat you, I think this is the origin of the pain/anger.

I have no solution as I deal with Anger myself.   It is not as physically severe as you describe your to be but it is real nevertheless and comes with a sense of hopelessness.

I have health concerns that my anger will eventually casue life threatening illness in my body/heart,etc.   I am 50 years old and would prefer to make the make the most of the time I have left on this planet, however my anger is really in the way.
