Never happened to me yet, but what happened to me was worse, I had a sudden burst of emotion and just had a meltdown in front of everyone in my class(crying and trying to kill myself)

, and then I shifted into a super crazy happy emotion

.
I told the teacher I had to go home after that and he let me call my parents
(later that day i went to the medical hospital and I got diagnosed with Bipolar DIsorder

)
