If you were the last survivor of world war 3, knowing everything you know now, would you still want to break your legs and gimp yourself to be 6'? No. You want to look better to get others to like you. Looking good has no purpose otherwise.
Not, I don't want to be "better" than other people, I want to be just as other people are. Not all people have the same feelings, I my case I just have a heigh dysphoria.
GIMP (a great photomanipulation tool, I recommend it so much) allows you to see how you would look being taller, but a simple mirror tilted can give you a great impression of that. Even a 10 cm step in front of a mirror can tell you how you would look after the procedure. In my case the look is great, I really like it.
CLL is not just a surgery, It's a hope for a lot of people. Of course, one has to be very careful, but that is still better than remaining short, because it gives me a bad feeling about my own body.
BTW: therapy didn't work on me, it has zero effect in my mind, I won't accept my current height easily.
