I'd say move to Japan and you won't regret that decision.
First off, Japanese average height is only 170cm or so in addition to their indulgences on being short. Japaneses are bluffing about their heights even less than Caucasians born in America, only 0.3cm and we gotta say maybe they are really not caring about height that much, unlike China and South Korea.
Secondly, 5'0 is unfortunately short all over the world and you gotta do LL to solve your height dysphoria if you don't mind me to say like that. LL can obtain you from 5 inches to 7 inches (Paley's Option 3) at most and 5'7 is not a bad height in Japan anymore. So if your money permits, try Paley's Option 3, which I'm also planning on.
Finally, listening to your body is the most important caution in the procedures. If your body can't tolerate the lengths, it will warn you against going on lengths with massive pains and other complications.
