How can I control this pressure?

I suffer from a mental condition called CSD (Chronic Stress Dissorder). This means I unwillingly bottle up most negative emotions... And with this, there's usually a means of venting, without exploding and doing something stupid.
But the problem is, there are always people who just PUSH and PUSH like they want me to crack, and half the time, I'm afraid I'm going to snap and tear out their throats... And as you can probably imagine, this is against the law... I've followed my psycho-therapist idea of using sports and the such to vent my emotions, but sometimes that not enough... And a professional opinion isn't always a right opinion, anyone any ideas how I can stop myself from hurting anyone? Mr-E

I have this in addition to a few different anxiety disorders. What helps me the most is stopping myself when you get close to cracking, taking a step back from the situation and taking a deep breath and looking at it from a normal point of view to realize that it really isn't a big deal at all. It gives yourself a moment to take control and always acts almost as a reset button for me.
I know what you mean about just exploding, you're driven to the point where you are physically out of control. I've literally thrown myself to the ground in frustration in fighting myself when it gets that bad and once again I just step back to see my situation from a point of view.
I don't believe what doctors have always told me about medication, breathing and counting, and exercising and eating special foods. The medication frustrates me more- the counting gives me time to build up the pressure further, like a hose that's turned on and you step on it and release it- and the diet and exercise thing is a hassle and shouldn't be necessary.
Its really just about fighitng yourself. It's a battle.

You've seen a professional on this and they didn't prescribe anything?!?!

I think you should see a different Psychiatrist. Medication can really help. Sometimes it may take a few tries to find the right medicine but in the end it's worth it.
