Help, My wife is struggling with postpartum

My wife gave birth to a boy 10 days back..me and her parents and my parents are here for her. But she is struggling with her post partum.

She is unreasonably scared and tensed of random things. She is scared something will happen to her parents. There was an instance of hallucination. She is crying all the time. She cannot sleep. Yesterday she slept for maybe an hour. She has cramps and pain which is harder because of the cough she had. She sometimes speaks like she is unhinged.

We are all here for her. We are taking care of the baby. I am scared of what is happening to her. She was such a bold sweetheart. I cannot see her like this.

People who has gone through something similar please let me know what helped
