I respectfully disagree with some of the things you said, them being:
- "India as a whole is bad." I didn't experience the invasion of privacy and irresponsible behaviour from Parihar at all, but I understand the generalization since most Indian doctors have proven to be awful.
- "2 inches isn't noticeable." 2 inches is a lot, especially for a 5'2 or 5'3 guy in India. With my duckass I'm less than 3" gained(let's say a little over 2.5") and it's a massive difference! You're sad about your friends not noticing, but if I were you I'd be happy. This means you can pretend like you were never 5'3 and just move on and live as a taller person. I wish nobody would notice I grew, but my height was one of my most memorable features so I'm sure it'll be brought up. I'm genuinely very surprised you say going from 5'3 to 5'5 in India wasn't worth it.
- "165 is average". It isn't for those that live in cities. India's average height is listed as 164.7 or something because it takes into consideration all the poor villages and the population under the poverty line, people you will never meet or socialize with. While 165 would be above average in say, a village, for male city dwellers especially of our generation, I strongly believe the average is at least 5'7. However 5'5 is nothing to bitch about. It's like being between 5'7 and 5'8 in US- kinda short, but not enough for you to be sad about it. Unless you live in Punjab, where the average height is 6'8.95.
Your 5'2 friend didn't mention your height because maybe he doesn't wanna talk about it? When I was 5'2 and one of my 5'2 male friends grew to 5'5(naturally), I didn't bring it up...goddamn traitor.
This is just my opinion, but I would advise against another LL. You say you can't afford internals and you'd look off proportions wise. You've struggled like anything and achieved a height you can most definitely live with. Don't fk it up with another surgery.
