When someone is diagnosed with gender dysphoria you are already ‘too late’. Damage is already done then, the person developed “gender stress”. Now the job is relieve the stress without imposing roles or assuming identities. This is the more true where it concerns minors.
Gender teams have a morbid focus on an imposed psychiatric disorder. Transsexuality or no transsexuality is go or no go. Unhappy but not transsexual? Sorry you are too light. All is focused towards gender reassignment.
