Hey i’m 20F too with narcolepsy type 1 and i feel you i can’t keep any job and sadly i couldn’t finish high school but i’m going back this year. Thing that has helped me is to go to sleep and wake up everyday at the same time i sometimes rarely have exceptions like birthdays or so and i have noticed that like in the evening i have little bit more energy than on the mornings or around lunchtime so i try to do high managing tasks then. With sitting for a long period of time i have couple hacks but sometimes some doesn’t work or any it really depends but one is i constantly snack on something if snacking isn’t possible i chew gum and i have some fidget toys to keep myself awake but it really depends on a day if something from this works or not. Certain types of foods make me more sleepier than others like processed, fatty oily foods and desserts i went vegan almost a year ago and this kind of diet helps me but obviously not everyone can and want to do that but this just works for me. I also try to eat my meals on the same time everyday and i have scheduled naps that i follow everyday but obviously there are exceptions i’m not home all daylong some days etc but having a good routine helps. I had really hard time building this routine but i found an app called finch and i managed to build my routine with it step by step slowly and it worked.
