Oh no! I hope you feel better soon. Being sick is the absolute worst.
SICKNESS BEGONE-
I reccomend drinking a lot of water, and if that's not easy for you try popsicles, icecream, milk, juice, gatorade, etc. If you can't keep anything down, maybe try light things like eggs, ice cream, rice, oranges, etc.
Also, when I'm bored, I either listen to music, draw, craft something, practice a routine (taekwondo, dance, gymnastics, etc), sleep, or watch videos.
I hope this helps and that you get better soon!
