I'm so sorry. It is awful having something like that, especially with a newborn.
When DD was 2 months old I got salmonella from tahini that was later recalled, and I puked for 8 days. It was positively awful. I don't know how I stayed hydrated enough to function, and probably should have been admitted for an IV. I was so worried about her getting it but thankfully she stayed healthy.
I hope you are feeling better very, very soon. Take care of yourself
