Dating anxiety

helloo, so for background i have never been in a relationship. I just went on an amazing first date with this guy. Super nice & sweet. He’s been nothing but great - BUT i feel myself freaking out when i should just be enjoying it ! i feel like i’m sabotaging it in my head. I don’t know what’s wrong with me - i’m just super anxious & feel like it could be moving too fast ? I don’t know, i do this thing where i find something not to like about the guy between the first & second date & kind of sabotage it. He is really nice & really cute & im trying not to do that but i just feel overwhelmed and it’s not even that far in! I want to see him again, we have plans later this week. I’m trying to just take it one date at a time & not think like 20 dates, or even past the next one. If anyone has experienced this & has any ways to mitigate these anxious feelings or just tell me i’m not alone in thinking this way that would be nice.
