I collapse when criticised :)

Knowing and admitting our problems is the first step to being able to do something about them. :)

Good thing you can speak it.

That doesn't mean it will be easy. Most things worth doing are not easy.

Yet since you have admitted perhaps you'll get better and better at noticing when that happens and the more you notice it and the quicker you notice it then it is likely it will become less and less of a problem.

Good luck with that.

I fight my own battles inside my own mind so I am describing my personal experiences about things I notice in myself. Maybe it'll work for you as well.
