Im 178 cm aswell. stopped growing when i was 15. Soon 23 years old and havent grown as much as a centimeter since then :) Was supposed to be around 190 like my older brother by looking at those charts as a kid.
I have learned to accept being short though and trust me when i say this, no real girl in an actual situation cares how tall you are. Sure there are plenty of memes and stuff like that making fun of short men but i have never ever met such a person in my actual life
