Cutting was unheard of in my youth. Now it's very common. Both DS2 and his girlfriend have a history of self harm. He had a potentially life limiting illness and her family were abusive. Cutting themselves was what troubled young people often did. They're in their early 20s.
When I was a teenager it was anorexia and class A drugs, and sometimes both. The young, particularly in affluent societies, have often suffered great angst. How they express that angst changes from generation to generation.
In the case of gender identity, the fact that, once medication is started, the young people affected are being steered into a future of sterility, no or diminished sexual function or pleasure, and lifelong consumption of strong drugs with lots of serious side effects leads me to think that this is one of the worst manifestations.
My DS and his girlfriend, like other young people I know, have recovered from cutting and now have nothing more damaging than scarring of their arms and/or legs to affect their futures. The same is not true for many, maybe most, detransioners.
