The biggest problem in this situation, as I see it, is this. The therapist may be acting out of good intentions, but the change she is imposing on you was decided without your participation. There was no prior discussion with you about the upcoming change. No one cared to ask you if it would be okay with you and what your preferences would be. You were basically told "this is how we will do it from now on because this is for your own good and because I said so". Do you know who is treated like that? Children. So, the biggest problem for me in this situation is that you are being treated like a child.

You are an adult. This is YOUR therapy and YOU are paying for it. You have the right to voice your preferences and to take part in deciding how your therapy will proceed.

No therapist can have intimate knowledge of your emotional process. Only you have that knowledge. Only you know what helps you become stable and what makes you unstable, what works for you and what doesn't.

If the therapist can't give you what you need for whatever reason, that's okay, as long as the therapist acknowledges it as their limitation instead of presenting it as something that needs to be done for "your own good".

It pisses me off when therapists treat their clients like stupid children who are supposed to obey and who have no right to make decisions in regards to how their therapy should be conducted while, at the same time, charging them an arm and a leg.
