I'm no psychologist, so I apologize if I'm way off here.

It sounds to me like you have some sort of need to be in control of situations, and when things happen that you can't control you respond with rage against the physical things you can actually bend to your will.

Did you have super strict or overbearing parents or experience bullying when you were younger? Anything like that which could cause you to feel so powerless and have such a need to vent your frustrations physically and tangibly against your physical environment?

I don't know what to tell you honestly, except to say that your behavior is definitely not normal. Lots of people feel the rage and anger you are talking about - that's part of life and certainly part of poker for some - but being unable to control such destructive impulses strikes me as indicative of a serious emotional problem. Talking to a professional really could help you work out whatever is causing it and learn to deal w/ frustration better.

Good luck.
