growli, there is a power dynamic in therapy and that is why Ts are trained how to handle the boundaries in a professional manner. the boundaries are primarily to keep you emotionally safe and secure. your LC is not a T and has not been trained how to handle issues like this and sure doesn't seem to be handling it well at all. becoming a LC is nothing like the training to become a T. Ts are aware they need to be consistent and establish boundaries for the health of the client. of course some do make mistakes but a LC doesn't even have the proper training to know how to handle this sort of thing.

you mentioned you have DBT and a school T. are you currently seeing either one of those or are they just available for you? can you reach out to either the group T or your school T?
