Your stature isn't so small. There's an FO at one of the regionals who is a midget. He probably had to endure a lot of crap, but he succeeded. Most in his situation might have given up or never even tried. When I first heard this, I was glad that someones physical trait didnt get in the way of a dream.
Don't let your size get in the way of flying, especially since it shouldn't hold you back physically at all.
