When I'm angry, why do I always feel the need to hurt myself?

because you feel the need to take the angry out on something which ends up being yourself. maybe try different ways to cope with your anger in a non harming way

People feel that when they are angry they need to hurt them self because they feel its a way to calm them self or to 'stop the pain' but it is not healthy and its a reaction your brain has when you get angry.

Because it's so easy to blame yourself! You don't want to burst out on anyone else either, because the risks to hurting their feelings, which also leads you feel horrible

Maybe is just the need of feeling something that replaces the old empty formula of anger, then pain takes the role as a drug, it becames the only single desire of releasing the anger in that very moment were dispair leads you'r thoughts.

I've gone through the same myself. Personally, I know it stems from my need to get rid of some of the anger. Some people bite pillows, some people break things, other people, like myself, don't like to be destructive, so we turn the anger onto ourselves. It's a way to make sure you don't hurt anyone or anything else, and the endorphins often help to calm you down. I've come to learn there are plenty of other healthy ways to cope with the anger aside from hurting yourself!

Self-harm is an unhealthy way to cope with overwhelming emotions. It can bring us back into the real world, and get us out of our heads. However, there are other methods of dealing with sadness, anger, and anxiety that are actually beneficial, such as journaling, meditating, exercising, etc. If you ever even feel the need to hurt yourself, tell someone trustworthy, and see what you can do about speaking with a mental health professional. Hurting yourself is not an answer.

Some people see it as some sort of outlet. A way that they can control what they are feeling. Maybe you are one of them. You just have to learn to control your anger.

It is like another way of telling yourself, "This is my punishment" or "It is better to hurt myself than others."

Without knowing you personally and without a lot of context, I can conjecture but it might be completely off base. Knowing others with anger management issues has me thinking that the anger you're feeling is at yourself, so you're punishing yourself

There was a time in my life when this was the case for me. Thankfully it isn't any longer. I'm not sure if there's any one clear reason why I did it. It sort of felt like the natural reaction at the time. I think part of the reason that I did it was that I had difficulty channeling my anger in any other way. I wanted to hurt something, but I didn't want to hurt other people, so I hurt myself. I also think I might have been trying to punish myself for getting upset in the first place. I'm not really sure.
