HELP! My face is SO dry and I have a date!?

I used some sort of acne face wash and now my face is horrible! Im having an allergic reaction or something and my face is SO dry that you can see the dry skin and its disgusting. Tomorrow im going out with this guy I like, its the first time ill actually be with someone nice and now my face is ruined! The only way that I get my face back to normal is if I wet it like, every 2 minutes. My face is so tight and stiff that I can barely speak or smile without it hurting and it shows more dry skin. What do I do?! Pleaseeee help me! Im seriously about to cry its so bad.
