Try mixing in corn starch. A tbs at a time. If it's really watery you might screwed. There is corn starch in powdered sugar. It's what helps thicken. You can also run regular sugar through food processor to make fine sugar but that might leave your frosting grainy.

@xMEGANANNx: take a tiny bit of corn starch and dissolve it in a little cold water... add small amounts while whipping it. It takes a bit, but it will start to thicken

Good Suggestion but being a liquid it would make it runnier :)
