I cannot last a full day awake

for as long as I can remember I was a napper. In highschool I would nap everyday in algebra 2 and if I didn't get that nap I would sleep in another class. If I didn't get that opportunity I would lie to go to the nurses office to be able to lie down and nap. When I got my first job, I use to go to the breakroom during my shift to put my head down and just take a nap. I never realized it was bad until freshman year of college when my romates commented on how often I sleep. I always brushed it off for having a bad sleep schedule and being depressed etc. Even now, I'm not currently working, only taking a few classes this summer, and will spend about 6 hours of my day at school, come home, take the dog out, and immediately go for a nap. It completely ruins my day because I usually will end up waking up at around 8-9 when the rest of my household comes home then I'm screwed for the night (not really because I love sleep). But its like as hard as I try I can never last a full day awake. I have days where I plan to stay awake for the day because I have things to do I have to literally tell my brain no nap today no nap today no nap today and still en up falling asleep. If I'm not up and doing a physical activity like going to the gym or cooking its over for me. If I even lie down in bed for a lil to scroll on social media or go to the living room I'm knocked out in 15 mins.

Last night I literally fell asleep on the floor because I was fighting demons trying not to sleep on the couch so I thought ok let me sit on the floor and watch tv... lol did not work

How tf does everyone last a full day I cant do it
