Rest, shelter yourself, and just really listen to your body. Last weekend I went to bed early, or when people are supposed to go to bed. I woke up about 12 hours later to go to the bathroom and then went back to bed. I woke up again at 6p, stayed up for a couple hours to watch T.V. and then I had to back to bed. I just felt exhausted.
Sometimes you just run into those days where you just need to get some extra sleep no matter how long that will take.
Don't think about what is normal or how others perceive you. You're in your own home, tucked away from everyone. You can do what you want. Think of how there is nothing to do. You are free to just be.
If you are not too tired try doing something you did for comfort when you were a kid. Like, watch hours of Cartoons, read a favorite comic, eat something that you haven't had since you were young.
One time, after dropping my daughter off at kindergarten, I spent the entire afternoon reading Archie. No music or T.V. for background noise. When I went to go pick her up I felt so rejuvenated and happy.
Anyways, just listen to your body. I think you need some rest and TLC.
