Can I just go to bed?

Prefacing this with the fact that I’m very new. Partner wrote me asking me if I could handle something today or tomorrow, and that if I could, they could give me details on the project. I wrote back saying I could handle it about an hour ago, and to let me know when they’re available. Radio silence since. It’s at the point where I’m passing out. Can I just go to bed? Should I let them know I’m going to bed? How “available” should I be?
