I agree with bringing this up with both of your Therapists. I see where they are coming from and how it may be beneficial for Therapists to work together when working with the same person; but I also don't see how this is fair to you. It really should be more collaborative and you should most definitely have a say in your treatment, based on what makes you feel comfortable. It doesn't seem helpful to take something away that was working for you. I would first ask for their reasoning and then give my input on the situation. Hopefully they will be able to meet you halfway to something they feel is effective and something you feel works for you personally.
