Hit my face today, concussion? Is it okay to sleep?

Long story short, I jumped off something, slipped, hit my lip and area by my eye, my lip bled a lot, and i felt like i was losing a lot of blood, and whenever i stood i saw colors and was dizzy. I didn't hit my head as much as my face, is it okay to sleep? Thank you. Don't tell me to see a doctor because at 12:09, while at a friends house, I can't do that.
