I would agree that there are plenty of mechanchim who should not be in “the business”. There needs to be more oversight whether it is through a mashgiach or other member of the hanhala (or guidance counselor in a girls school). I have seen a couple of really bad apples in my day.
there is no reason why you should be forced to accept a substandard quality of life. Finding a mentor is a must and it does not have to be someone in the school it can be an older person you can vent to and can identify with you and give you advice. Take it from someone who has a been in a similar situation many times before.
