No therapist will leave abruptly. If you have paid for it.

What was the conversation which was left in between? And what happened to you when this happened.

There could be some personal issues sometimes there are urgent calls as well

Hi... What do you mean by 'therapist escape the session' ? Did the session started and then s/he left the session without informing or the session didn't started? A change in appointment is intimated minimum 1 day/24 hrs in advance from either side (client/therapist). But in some personal/professional life exigencies, such last minute changes can be accommodated. Although doing it often without proper intimation is unprofessional and unethical for either side. A Therapist may also leave or discontinue a session abruptly if s/he feels threatened by the client. I hope that wasn't the case.

There is always 2 sides to any concern. One cannot see things in absolute black and white. It is indeed a psychological distortion. Please introspect
