Have you ever had an experience where you were under extreme stress(& I mean EXTREME)?

-This can easily be a period of several weeks
-you constantly felt like throwing up
-you had a lot of questions on your mind
-it became so bad that after a point you basically were acting on your impulses and were acting irratically.
-you were frustrated to the point that whatever you said was basically the first words or thoughts on your mind no matter how ridiculous it sounded.
