I usually don’t dive into these psychological topics, but after a recent MLP short came and went I wanna know…
 
Can a fear/phobia drive a person to the brink of insanity?
 
For example, say a person has arachnophobia (fear of spiders); If they were to experience this fear over and over again, would they eventually snap and go nuts? (Possibly to the point where they wind up locked away in a mental hospital with a straight jacket?)
 
Please let me know what your thoughts are.

I had three anxiety attacks over the course of a year (not this year) that was not doing my mental health any good. Had to get counseling because of it. Been going for almost a year now and it’s really been doing me good.
 
Panic attacks are the worst.

It definitely can, it’s all about the time the person has been into the fear/phobia and how it reacts to it. Sometimes people can get over their fears by battling them and sometimes they need special help. Just like how the short showed us.

Last year I developed a fear of dying at any moment that would drive me nearly insane, kept me up at night, and physically hurt me and made me even sicker.
