I think if people contacted their psychiatrists whenever they felt really anxious, then psychiatrists would just be bombarded 24/7 and wouldn't be able to handle it.

It is a frustrating issue to be sure, but from the perspective of your psychiatrist it is definitely not worth contacting them over. A therapist, I could understand. But even then, it is better to use coping mechanisms yourself to get through this. I don't mean to be harsh or minimize this relationship issue, but I think contacting a psychiatrist because of this is not necessary or helpful.
