Not sure what is going on in you therapy but just because your T wants you to do something doesn't mean that you have to. This to me would be simply subjecting you to further abuse. Also, you might look into your college Student Handbook. Every school is different but, a student refusing to talk about their abuse is not grounds for dismissal. If you are at risk of harming yourself or others, now that might be grounds for sending you home.

I would suggest that you speak with your T. Let her know that you've gotten her message that talking about the abuse is important and necessary, but that at this point you are not ready..so stop pushing. If she cannot do as you ask then maybe it is time to work with someone else.
