So i got asked on a date for Valentine's Day tomorrow and it's my first date ever. I really really don't want to go. I already said no to a date with him the last time as I was ill but he asked again and I couldn't say no. I like the guy I'm talking to a lot but I can't explain how cringey the concept of eating in a restaurant is to me. It makes my spine shiver. Not to mention I am SO nervous. How do I act? What do I say? Im scared I'm going to be an awkward mess. It's so cringey to me that you have to eat in front of them and try to impress them. I'm a weirdo lmao I guess im just asking how to get over my nerves and how to shake the cringey feeling I get when thinking about going?😊
