Audible snap inside head then no emotion? - Preferably someone with science/medical training please/thanks?

In a moment of severe stress+emotion something audibly snapped in head/brain --> total sudden void of emotions --> over subsequent days my emotions only returned to ~10% of their original level, and also noticed my wheezing reaction to dairy was the same (only ~10% of original amount) --> 2 months later no improvement Anyone heard of something like this/have any idea what could have happened?
