The NP sounds disorganized to me, for several reasons, but mainly because she did not have your appointment recorded after you both shared a consultation over the phone. The mess of the house and the boundaries are also sloppy and inconsiderate, as was her handling of the dropped appointment, which was, after all, her own mistake. She may be juggling just way too much. Sounds like she doesn't have time to tend to a small, urban front garden.
If the NP is any good at getting results for people, that may be why she's busy, but she is obviously "hairbrained" and not for everyone. How she treated you, for instance, is not compassionate or, in my definition, professional. Furthermore, I think your T. should let her know her mistakes (at least three: garden work in open view; not handling appointments well; common courtesy for someone with a service animal (who asks politely for her help).
Since you had a phone conversation with her for fifteen minutes, I should think she'd remember your voice or you on some level. Because she is so scattered, this seems like she's allowed her life to become unmanageable. I suspect she is what some call
codependent, (for lack of better term for this personality).
By the way, I agree with
@sun seeker that your messages do not seem long because they are well-written, organized and relatable. I hope that your communication strengths continue to work for you and create even better healing opportunities.
