Transition things that get severely underestimated and disbelived

The emotional harm done to us by forcing us to wait years, all the while begging for doctors and therapists to deign to provide us even basic care, all the while they insist that these cruel delays are good for us because "you appreciate your transition more this way!" when, in reality, it's that they don't believe us when we say we're trans but have no objective way to decide it beyond our own words so take the approach of "if they don't give up after enough years then maybe they really are trans...but we'll never be fully convinced."
