Wow, that's annoying that she's supposed to be a "specialist" but still appears to invalidate you and your identity. Trying to talk or write to her is probably still worth a try. Although lecturing a trans person about dysphoria is really a no-go in my opinion.

With my therapist it was more the omissions, the things that he didn't do or say that made me feel like he was invalidating me. But I know that the way I was perceiving of our relationship was definitely affected by transference (so when he didn't actively validate me, a lot of alarm bells went off on my end). Although he did say to me I wasn't dressing in a particularly masculine way. Me: Everything I wear is from the men's section. Him: You could wear a tie. Me: YOU'RE not wearing a tie.

Lol. Some of the dialogues we have had were pretty absurd.

Anyway -- I hope you can find what you need in terms of therapy, with your current or a new t! Keep us posted how things are going!
