Please help😩

My baby girl is 8 days old. I’m breastfeeding exclusively. It’s so hard to keep her awake! She wakes every three hours to eat most times but mostly I have to wake her. It’s SO hard to wake her up. I don’t know what to do I can keep her on the boob for a good 10 minutes today and after that she’s out and won’t latch again unless I make her cry to wake up. Is this normal? Do babies really sleep this much! I was not expecting this at all and I’m scared. She sleeps all day unless she’s eating and usually has one time a day where she’s wide awake and just looking around. I’m new to this obviously and just want some reassurance 🙁
