This is why you have to learn to detach. When I'm feeling really vulnerable, I try to pretend I'm an actor (preferably a bad one) in a role and as I see things unfold I try to remember to breathe before I speak.
I know what you mean about not being able to take it. My H got all pissy on day this weekend and wouldn't say a word. I stood in front of him and (as casually as I could muster)said "Did I do something inparticular to make you mad or is it just b/c I'm breathing?" His response was "no". Beats me. I went out.
