Is what I'm feeling normal?

I just had my baby on July 27, a few days ago, and I haven't gotten much sleep because of how much he cried and I was held at the hospital for 48 hours. I got home today and my baby is sleeping, but no matter how exhausted I am, I can't seem to fall asleep. I thought my heart rate might be a little weird, so I took my pulse and it's fine. I don't have shortness of breath(I have to clear my throat a bit though, but that's normal for me). I don't know how to describe what I'm feeling right now. I'm not sure if I'm anxious or what, but I can't sleep and I really would like to. 😔 anyone else have similar feelings after having their babies?
