I don't have bipolar, but I can relate to your diagosis being questioned. My diagnosis of autism spectrum disorder keeps being questioned even though I've been assessed a few times. Doesn't help that y parents, who are in denial, claim that the psychologist who did the most extensive assessment, said he was only sticking the label on me because I needed services.

Anyway, I totally relate to feeling upset for days whenever I'm invalidated like this by a professional. I mean, it's really invalidaitng your experience to blame your mood disorder on alcoholism, anorexia or whatever other than bipolar.
