too nervous to try

Ok so this guy has been wanting to hang out with me for a while and I finally said yes. But now I don't want to. I feel sleepy and I hate my hair, I'm cleaning my house now. And I don't want to flake. But I'm nervous. What if I don't like him?.. what if he thinks my house is gross... or I'm gross? Idk why I agreed. I think I should just not text him back. He's cute but I can't..
