Do you ever feel contempt or aggression from your therapist?

You know it's faulty thinking. Indeed, it's #3 most common cognitive distortion

Of course you allowed yourself to become vulnerable.
Do you really think that you can go to therapy without allowing yourself to become vulnerable with the therapist ?
If you weren't vulnerable, would you need a psychotherapy at all ?
If you're not sick or in need for administrative medical paperwork, do you need to go to the doctor ?

Saying "I'm at fault because I allowed myself to become vulnerable with a therapist during a psychotherapy" is exactly like if you stated "I am at fault because I made an appointment with a lawyer for writing an affidavit and I allowed myself not to know all the legal details about affidavits".

Giucy, you make me laugh
