Ha ha ha...my mom always told me...you are going to find similar crap within any company if you are in the same position, no matter where you go. The only way to escape it is to change positions/professions. From everything I have seem she is SO RIGHT!
I say if Psychology is something that will get you out of the rut you are in and something you interested in, then go for it!
Maybe one day things will come full circle and you will have the pleasure of committing some of the nutters you work with now!
In the meantime, just repeat to yourself, "It pays the bills, it pays the bills..." Hang in there, the day is half over.
