I feel like my newborn hates me

I know this is a symptom of PPD. I don't want to harm him or myself. But I have been consistently sick with one thing or another since leaving the hospital (sinus infection, stomach virus, my back went out a week ago and still hurts). Because I have been so sick, we have been staying with my parents. I feel like he likes them more than me. When I hold him he cries and screams and as soon as they pick him up he stops crying. It makes me so sad and I'm not sure what to do. I take care of him the majority of the day and I get up with him all night, but it feels like he's more attached to them than me 😔
