I can't help but wonder how much is attention seeking - wanting to feel special, different - which is a disservice to those who really would normally have this... Condition sounds negative, but I'll use it for lack of a better term.
The bigger question for me is how could we sort between the two, and should we want to even if we could. Gender transition, and genderqueer presentation are relatively harmless ways to alleviate pain.
Also, boasting about being broken, having depression, mental issues and suicidal thoughts is now frowned upon, so gender dysphoria has covered that vacuum. Before that it was geekiness.
Maybe this is society's growing pains as it learns to cope with social media.
