Does anyone else have such a resistance to bedtime?

If I don’t plan to sleep or know it’s just going to be a short nap, I sleep quickly and peacefully, but whenever I know I have to sleep through the night, I become super anxious and unwilling to go to bed. It almost feels like fomo of feeling like the idea of sleeping for 8 hours straight is too much pressure and I can’t commit (funny thing is, I never sleep that much anyway lol but that’s how it feels in my head). Ugh it’s distressing though, anyone else struggle with this and any suggestions?
