Aww, you won't pass out from a shot. Think about it a peircing says it all it peirces, goes completely thru. A shot is a quick, barely anything poke. If you got the tattoos w/o passing out and have never but w/ the navel piercing than I'd say you're gonna be fine w/ a shot. Besides when you had your belly button done it could have just been coincidence and a combo of things that led up to it and the peircing was the last straw. You'll do fine! And you don't suck, you're just scared.
