No I know its not unique to transitioning, its human nature, like how people become institutionalised.
Which is why I feel setting them onto this path to begin with rather than trying to prevent it from happening is dangerous.
Ones identity should not be wrapped up in one thing this way, and is something that is usually advised against and other outlets and broadening interests etc is encouraged.
Hard to do that though when identity is the end goal, proof amongst all proof etc
Sorry not explaining myself very well...
I guess its a bit like picking a career... not only would you need a plan B, its all very well putting all your time and energy into achieving that, but it should never be at the expense of everything else , friends, family, hobbies etc amd In fact might actually count against you in the end..
