Anxiety post FTM

I had my baby last week at 35&4. It’s flu and Rsv season and my anxiety is through this roof figuring out how to make sure he stays healthy. I know the basics- no visitors who are sick ( were only allowing close family visit anyways ). Washing hands and sanitizing. Etc etc. but my anxiety is still crazy. I went out in public by myself for the first time and I came home and sanitized everything ( phone, etc)& took my clothes off before I held him. I also spray some Lysol in the house. I don’t spray in the room he’s in for a while until I take him out. They say when he’s 6-8 weeks we’re ok to go out in public but I don’t even want to try then. And it’s the holidays by then as well. Is there anything else I can do to prevent any sickness that could get to him? Also, if I get sick how do I handle that since I stay home with him. Sorry. I’m a FTM& I have really bad anxiety 😓😓😓 I need some mind easing.
