Also, It would be interesting to know what exactly that student did in order for you to assume your life was in danger to begin with, what did he do in class so you got forced into cancelling it all? did he pointed a gun at you ? did he threaten you with a knife ?

By the way, I don't understand why you are being to mean against me I am just trying to understand what went wrong and what happened so you got fired from being a professor, I am not even insulting you, but it seems you continue to bark insults at me instead of being reasonable and keep a conversation as a rational human being would.
By the way, you don't even know my level of education or where I studied so it is kind of random of you to even mention my education being worthless.

Haven't you tried to contact you local mental healthcare provider, by the way? As far as I know all States in the USA are supposed to have facilities designed to provide help to people like you, you could manage your anger easily if you were more open minded.
