Hope, he's your pharmacist. It isn't about him hating you; that's an extreme reaction. But you are simply a customer of his, one of hundreds and hundreds of customers not to mention doctor's offices, etc.

You seem to be really fixated on him, and if he has picked up on it, yes, he is probably going to find a way to put up a boundary there in order to keep the interactions professional. I suspect we are at the same pharmacy at least once a week, and we have been for probably 20 years. It is VERY rare that we specifically ask to speak to the pharmacist about meds. We address our medication questions with our prescribing physician first. In fact, generally when we do speak directly with the pharmacist, it is the pharmacist himself/herself who initiates that conversation simply because of protocols about being sure we know the meds, etc.

You do seem to have a pattern of initiating a lot of contact with authority figures (therapists, pdocs, pharmacists) about things that probably don't really require contact, and in several cases, that excessive contact has ended up creating problems for you with those authority figures (and certainly creates repeated internal stress for you). Have you worked with your therapist on this pattern?
