What are some signs that a therapist may have poor boundaries with their clients?

Struggling with fantasies of deeper connections with clients, whether sexual or parental or other intense or intimate relationships beyond psychotherapy.

Obsessing about clients outside of work hours.

Failing to mention the client in supervision/consultation, out of fear the supervisor/consultant will advise return to ordinary healthy boundaries.

Is it recommended to leave a note in a lost wallet asking for it to be returned?

Off the top of my ancient head:

Session-expressed curiosities about client details not relevant to the therapy.

Disclosing feelings, fantasies, and experiences to the client in ways not related to the work the client is engaged in.

Why is every human messed up in some way?

Routinely going over the time limit with certain patients, compromising the time for the next client.

Eager anticipation (or anxious anticipation) of the next session in ways that distract.

General Introduction to Boundaries from Panahi Counseling:

Why does everyone hate Anthony Joshua so much? I get that he isn’t the best heavyweight boxer ever but people claim he’s a no skill fighter but he has an Olympic gold medal, a world championship, and beat Klitschko, a dominant force in boxing

Serious disappointment when the client cancels a session.

These items can happen fleetingly, briefly, in any therapy, but if they’re frequent, it’s definitely time for the therapist to get some good, solid supervision/consultation.

Sense of competition with persons who are important in the client’s life.

What one thing makes someone a very mature person?

Frequent phoning or texting of clients to “check up on them and make sure they’re OK.”
