Fear of falling off a skateboard?

I love to skateboard, i just wish i was better (obviously). All of my friends skate and I'm pretty much the only one who can't do a whole lot. All I can do is ollie and manuel and easy stuff like that, but im scared to push myself into doing flip tricks. I always land with one foot on the board, I'm just scared of falling I guess but I play paintball and airsoft so idk if pain is the big issue, please help.
