I'm trying not to panic, but I'm noticing an increase of pain in my chest lately. It's usually for me a very bad sign, a sign that I'm going to have a break down soon. What can I do ? It hurts and I'm scared it's going to hurt more and more until I explode with pain. I experienced this two or three times a year, when this pain grows and grows for a week until it's unbearable and I explode and dissociate. But this time I don't want to do that. 

Also there is absolutely no trigger that I can think of. Maybe stress, but no interpersonal issues. It's not a panic attack, it's different.

Things that doesn't work : sports (usually it makes me more calm, but with this it makes me more agitated), cold shower and trying to accept the feeling (although I admit I'm very bad at this). Distractions seem to only delay the crisis.

Anyone has an idea ? What can I do to stop this without a crisis ? I hate this !
