A head explosion is when you head makes a sound almost as loud as a gunshot or an explosion (Hence the name). It means my body is saying I'm taking too much stress, and I need to stop whatever is making me stressed. Well I can see the problem... SCHOOL... more specific HIGH SCHOOL. Today my day really sucked... I got bullied by some upperclassmen on the bus, I got bullied in class, my locker got jammed causing me to be 15-20 minutes late for lunch and I almost didn't get lunch, also I got the in the right class at the wrong time so I got embarrassed... more bullying... I forgot my one of my french papers was homework... blah blah blah. So basically I'm getting too much stress from high school, this will cause some complications to me because I'm very emotionally unstable.
Tl;Dr, School is causing me to have too high stress levels.
P.s. (I forgot to mention this is my 2nd day...)
