Based on your posts, it seems your T is trying to get you to be more indpendent, in my opinion. However, it appears toj be backfiring massively. You have a right to tell her that this is not working for you. I don't know her motivations for being so harsh, but if it is hurting you, then she needs to knock that crap off and find a new approach.
There's a reason you need reassurance and you want to call her and all that. She should be exploring that with you to help you grow stronger, not fussing at you about it.
Remember why you are in therapy and keep your goals in mind. Maybe that will help you.
