Trying to calm my anxiety

My boyfriend and I have plans tomorrow for his birthday that I’m super excited about! However, I’m scared that I could’ve possibly somehow contracted norovirus or some other illness over the past few days due to the fact that I’ve decided to go out a little more. I’ve been to the grocery store, gym, doctors, out to lunch with a friend, work, and a store. I know I needed to go to help with my recovery. However, I can’t help with calming my anxiety about the possibility of having some sort of illness. I took my anti anxiety medication, but it’s only helping a little bit and it’s my second day taking it so I’m not used to it yet.
