My honest remedy (being between 5 feet even and 5'2' depending on where i am, and what measuring tape) is to use it to your advantage.
Being short allows you to not only go unnoticed by the tall people, but also amazingly good a finding good hiding places. Free rides (piggyback, etc) are also an advantage to being short. It also helps then the lift the robot to do work, and you're the quickest one under it, since you're lowest.
The thing that has made me grow, sleep, lots of it, and a lot of milk.
Also, stretching, and exercise. Does amazing things.
stop thinking about it, that sometimes helps
try not to stand next to the tall people, and if you do, get a chair, table, stool, etc to stand on
