Rollercoaster

I dunno if it's the hormones or just the fact that I'm mentally and physically exhausted like all the time. My emotions are out of control. Like I was grinning all through lunch and then after that calc quiz I could barely drag my feet. The ap gov free response kicked my butt and then i had a physics lab but I felt good chilling with my friends while trying to figure out how the vertical velocity has anything to do with the volume of the water. (not usually). Well for backup I also pack candy when I'm feeling low. Any advice?
