In general, it is considered unprofessional and unethical for a therapist to abruptly leave during an ongoing therapy session without a valid reason or proper termination process. The therapeutic relationship is built on trust, and such behavior could be harmful to the client's well-being.
There are some situations where a therapist may need to end a session early or take a brief break, but this should be done in a planned and respectful manner. For example, if the therapist becomes aware of a personal emergency or a critical situation that requires immediate attention, they might discuss the situation with the client and either reschedule the session or arrange for another qualified professional to take over temporarily.
If a therapist consistently leaves sessions without good reason or neglects their professional responsibilities, it could be a sign of burnout or other personal issues affecting their ability to provide care. In such cases, the client may want to consider discussing their concerns with the therapist, seeking guidance from a supervisor or professional licensing board, or finding a new therapist if they feel their needs are not being adequately met.
It's essential for therapists to maintain professional boundaries and prioritize their clients' well-being at all times. If you ever encounter a situation where your therapist behaves unprofessionally or you feel uncomfortable with the therapy process, it's essential to address your concerns and seek appropriate support.
