You're more than capable of dealing with the short slices, Chederer. You just need to play someone in a few friendlies and ask them to help you practice countering it. Better to do it in a friendly when you're prepared for it - it let's you focus on what you need to do, rather than letting the anger take over.
Once you get used to countering it, you'll rather play someone who uses it constantly than someone who mixes it in - it's easier when you know it's coming.
