What’s a normal amount of postpartum sadness?

6 days postpartum and I’m scared that I’m showing too many signs of postpartum depression already.

We got home from the hospital 2 days ago and I just can’t stop crying. I feel so disconnected from everything around me, can’t stop sobbing, and just am soo tired all the time. I’m not crying about anything, just randomly start crying.

I expected to be tired and more emotional, but I feel like a shell of myself and I’m so scared it’s not going to go away.
