A few days ago my boyfriend and I were driving around. We had conflict earlier in the day, so I was extremely stressed. I accidentally had him drive us to the wrong place. On top of everything else I already felt bad about that day, this was another thing. 

On the way to the correct address, he asks me:

"Are you making yourself feel bad about the mistake?"

I told him that I just felt bad. That I didn't feel like I had any control over it despite trying not to. That I was just stuck. I said all of that snapping with a frustrated tone, because I feel like he faults me a lot for this. I get into a state of feeling down on myself or I emotionally shut down. He wants me to get out of it immediately. If I don't or can't, he claims I'm not trying. That frustrates me even more and makes the cycle worse. What should I do? I'm tired of being told I'm not trying or expected to just snap out of a bad mood instantly. I know my feelings are on me, but sometimes I feel helpless to get out of them. I feel like I mentally shut down under extreme emotions or stress. That no matter how hard I try to snap out of it, I can't form coherent thoughts or think at all. That my mind and comprehension is at a stand still. If I don't get out of that state immediately, I'm faulted or blamed. Any input would be appreciated.
