I am sorry you have to go through this, it sounds so incredibly frustrating and it is understandable you are feeling as you do.

I don't know if you are "too attached"......what does that look like anyway? I am not sure how it is that your tutors are able to dictate who you receive your therapy from? Especially as your therapist is of a differing opinion to them about the effectiveness of your relationship.

And..... if you are too attached, would it not make more sense to work this through with your current therapist, would there not be far greater learning in that??

I hope you can resolve this, and that you feel better soon, This does suck!
