I have bipolar disorder like bpcyclist above. My therapist and psychiatrist are also incredibly supportive and kind. They recognize the challenges related to my illness, and yet also recognize me as a person, separate from my diagnosis. I'm not sure why you would think that other therapists and psychiatrists wouldn't care about patients with diagnoses other than yours. Of course there are some uncaring ones out there, but that, in my view, would reflect their individual personalities rather than professional viewpoints.

Going beyond mental healthcare professionals, yes there have been people that treat(ed) me differently because of my diagnosis. That is sometimes because I am on disability and other times because of fear or discomfort, and other times stigma, etc.
