Reading through the comments and what not, I personally believe it has more to do with the way you see yourself.
Your height isn't a problem.. It is a normal height.
you are basically a few cm's taller than few most women out there, so your height wouldn't be a problem. Me on the other hand, 5'6 1/2. I struggle highly with confidence ..
What your problem is, is the way you see how things work.
You don't
necessarily need height to attract a date.
I mean look at Zac Efron, he's the exact same height as you and women will do anything to spend time even close to him..
You could do better than a risky, dangerous surgery for something that can be overcome in safer ways.
Many people actually suffer from depression because of their height, Only then you "could" say it's reasonable for them to undergo the procedure..
How about, you visit a shrink, Give yourself some time to truly think about it, and then decide whether it's that important or not.
Wish you the best mate.
