Please take a deep breath and calm down. A therapist who doesn’t know you ventured an idea. It’s only an idea. The person you should be talking to about it is your regular therapist who knows you well enough to make an informed opinion. If your regular therapist won’t be available for a time, you do have several choices: You can wait until your therapist comes back to continue your therapy. You can talk to the new psychologist about what led her to her idea. Or you can seek out a different therapist to support you until your therapist returns.
Do remember: Therapy is a collaborative process. You don’t have to accept everything any therapist says. It is just wise to think seriously about what is said and to participate in teasing out what is true and what is not.
I wish you well.
