Crying With Frustration ALL THE TIME Even Over Simple Things

Does this happen to anyone else?

I get extremely frustrated very easily and I always start angry-crying. Every time I hit a wall at school or at work, I almost immediately start to cry with frustration. I also get physically uncomfortable with that kind of panic-sensation where you want to pull your hair out or scratch your arms off, etc.

I don't know what to do about it. It's literally taking over my life and considering it happens at the first inkling of not being able to understand something (literally if I don't understand something the immediately the first time I read it, I freak) it's happening multiple times a day.
