Does anyone else stay up late into the night even though you’re tired and need to sleep but don’t want to lose any of your free time?

I’ve noticed i do this almost every night, even though i’m at home 24/7. I graduated three months ago and i havent been able to get a job so all i have is free time but still i make myself stay up to 4-6am every night and wake up around 10-11am in the morning/noon

I’m wondering if this could be a symptom of my BPD or could this be something else?
I also have a huge case of fomo (fear of missing out) if this is even worth mentioning 🫠
