I used to get angry like that (uncontrollable) when I was younger, but soon found that it didn't really get me anywhere, except exhausted, depressed, and alienated from family and friends. I think I've "mellowed out" a bit now that I'm older, but it could be that I'm using better coping skills, too. This is what I do when I feel that kind of rage coming on:
1) I literally count to 10 -sometimes out loud even- to slow myself down. I take deep breaths while I'm counting and try to focus my thoughts on something that makes me feel happy and safe, like being with my cats or driving in the country. I think foreverhopeful uses a similar technique and calls it (appropriately) her "happy place".
2) If I'm around other people, I will immediately leave the room...no exceptions! I do this to prevent myself from doing or saying something I'll regret later.
I've also found that if I give myself some time to "decompress", I'll be able to think about the situation more rationally and realize that it's not as big of a deal as I originally thought. This also gives me more time to think about a way to deal with my anger more appropriately, like through communication, rational confrontation, or taking action.
3) If I'm by myself, I will go into my car and scream as loud as I can.
I usually feel a lot better when I do this and I'm not hurting anybody...or damaging any property.
4) I've found that for myself, it helps if I deal with the situation or person who's made me angry as soon as possible (after I've cooled down a bit), rather than bottle up my rage inside.
If dealing with a person, using "I" statements help a lot, such as " I feel hurt when you...." or "I know you meant well, but I get very angry when you....". If dealing with a situation, if there is something you can do to change it, then make the necessary steps to do it. If there's nothing you can do to change the situation, then let it go (this is harder than it sounds, I know).
5) If you find yourself becoming enraged a lot
, you may want to do some self-observation to figure out why you're feeling this way. Or if that doesn't help, you can make an appointment to talk with a professional counselor or therapist on how to resolve your anger.
Hope these few tips help. Many (((hugs))) to you and I hope that you'll be feeling happier soon!
