I have a phobia of spiders - its my only phobia I know of - but it is extreme.
I literally freeze up when I see one.
Add to that the fact that my zoology background forbids me from killing them (unless they are extremely poisioness and a danger to others in the
household) and its a harrowing combination!
It is too bad that you were exposed to such abuse - but I wonder if there isn't some kind of treatment that could help reverse the psychological
Being that so many social events are centered around eating that can not be a small inconvenience.
Since I have OCD I have to force myself to use public bathrooms so as to not cancel on seeing movies, going to happy hours/dinners ater work, etc..
(but I do find that it works - even if I have to take a shower when I do finally get home)
I know for lots of phobia's increased exposure to the phobic situation causes desensitivity to occur in the brain - but I don't know if that would
work in your or my case.
Maybe it would. Either way you mite consult with a professional sometime concerning your condition sometime.
