Chicken crazy

Please tell me I'm not the only mom who, when sees blood, completely loses her cool and almost forgets how to be a good mother. Instead of thinking, I run around the kitchen like a chicken with my head cut off trying to clean blood flowing from my girls mouth as she screams bloody murder! Do I think to stop and assess the situation? No. Do i think to calm myself down so my daughter isn't feeling my stress? No.
I often joke that my husband is the only reason I'm even a semi stable person, and the only reason our kids will be, but my joking is based on complete truth!
It's in these blood soaked chicken runs where my husband steps in and helps me regain, or is forced to take control.
Interestingly enough, I am well aware that head wounds always gush blood and my daughter cries over "booboos" which happened over a week ago. But even with that knowledge I go chicken crazy when I see the combination.
So why is it so hard in those moments (and many others if I'm being honest) to set emotion aside and plug into that thinker??
