Am I being unreasonable?

So my cousin is pissed off because I don't want anyone at the hospital bc December is the worst part of flu season and I'm just scared and don't want anything to hurt my baby. And she is not considerate at all anyway, last time she came over she was very sick and failed to tell me

That before coming over and just did nothing to prevent me from getting sick and pregnant women have a low immune system. She was leaving her nasty snot toilet paper around my house and all kinds of gross stuff and left it for me to pick up. And I kinda just want it to be me and my husband anyway cause I'll be tired and I don't want all the stress. There are so many reasons I don't want visitors at the hospital. And also shes not even engaged or having a wedding so she was just saying I was probably not coming to her wedding one day just to be saying something to piss me off.

Update: just thought everyone would like to read the rest of the conversation.
