Is it normal that i get insanly angry when i get scared?

I find that whenever I get extremely scared, I go into a fit of rage. I normally bite my tongue when I'm angry even when the person I'm angry at knows and tells me it's okay to express my feelings. When it's annoying things that aggrivate me, I just complain. When I get scared, I either want to hide or beat the stuffing out of something. The most recent example of this is, this coming semester, something got screwed up with my financial aid/ payment plan for college, ending with my schedule getting screwed up. I kept mainly the same classes but at different times and I had to exchange one class. When I found this out, I was so angry that when I had a slight feeling of numbness in my head, that warned me to calm down. IIN?
