That would bother me too. It is concerning that she believes such a thing. It's more concerning to me that she didn't have the objective perspective to know how potentially inflammatory sharing that information could be. It was not a good choice to disclose that. If she thinks it, keep it to herself!

Not certain if her intention was to empathize with you. So I encourage you to talk to her about it. Maybe send an email, so it doesn't take up your therapy time.
