Honestly I would just try and let this go. At the end of the day no matter how much you liked her or thought she was personable, it’s her job. I’m sure there’s strict rules on developing even friendships with patients, and her job just isn’t worth the sacrifice. I’ve had many friends say they wish they could befriend their therapist, I think it’s just the nature of having somebody listen to you unbiased, offering advice and reassurance. We all want our friendships and our partnerships to be like that, it’s an attractive quality. I know you said it’s part of your condition that you over analyze these situations but truthfully you are better off just moving past it. I also wouldn’t doubt yourself, if you felt there’s a connection there may well have been, but the likelihood is just that you truthfully were reading into it. Hope you’re feeling okay!
