Psychiatrist evaluation prior to breast reduction

Hi! I’m in the early stages of booking my breast reduction, but I’m required to have a psychiatrist evaluation prior to the surgery due to my history of body dysmorphia and eating disorders.

I’m really worried about it and I’m scared they’ll tell me I can’t have one. I know that I’m mentally stable and capable and doing it with realistic expectations. I’m autistic and I tend to overshare and over explain and I’m honestly just really nervous about the whole thing.

Does anyone have any experience on what it was like for them and if this is usually a barrier or if people usually ‘pass’ this evaluation?
