Therapists deal with termination all the time. It’s an inherent part of the job. So you really don’t have to think about how they will feel. Then again, I highly recommend sending an email or text saying that you’re terminating because a majority of therapists will charge you the full price of the session if you just don’t show up to your appointment. Also your therapist is gonna need to follow up with you if you do anyways so you might as well do it on your own terms.
