Very "cold feet"

Ok, now I'm freaking out.

I found myself engaging in numerous random, seemingly involuntary movements while studying. I only do that when I'm nervous (and completely out of sorts).

Right now my Self-efficacy is superbly low.

Self-efficacy: The belief held by an individual that he is able to execute a certain behaviour in order to attain some goal. The ability to summon one's resources, cognitive, motivation etc. to get through a long process filled with barriers. I can't even get myself to put in lots of effort.

My English suck.
