From what im reading, its seems as if its unlikely that i would be able to become a pilot.
Rubbish!
I'm 5'3" and fit quite happily in a C152/172. My PPL instructor was the same height as me (she still is, come to think of it) and she now flies Dash 8s. I know a Twin Otter captain who's even shorter than me.
Your height is no problem at all.
