Good luck!
Unlike many, I was lucky in the fact that I wasn't nervous. I knew I could do it and was as confident as if the Instructor was there with me. You will do fine. Your first landing will either be horrible or great (mine was awful, I landed on the nose wheel and got a good bounce, plane feels different with only one body in it).
You know you're capable of doing it - if you weren't, the CFI wouldn't send you up. Just keep that in mind.
