Anxiety and pregnancy

Today was the first day I experienced irrational pregnancy anxiety. We own a restaurant and my dad and brother went there to check up on it and get me some food. Apparently they pulled up and outside of the car was poop with dirty surgical gloves next to it. My brother said it looked like a person took a dump there. He went in and got the food. He told me this when he got home. Just to tell me a story. Old unpregnant me would be like ew gross and just brush it off. But my mind started spiraling and was like omg what if the poop got in my food., what if the employees put poop in my food because they don’t like me ( they don’t have any reason to tamper with the food). I found my self fixated on this for majority of the time after eating and any time I was happy this thought would pop into my head today. I’m a single mom currently living at home with my toddler. I’ve been stressed and trying to keep it together lately. I’m 7 months pregnant. Does anxiety heighten during pregnancy? I don’t remember this with my first child. I also wanted to cry just walking in to the grocery store. I’m also finding it hard to parent my toddler. I’m trying my best but lately I feel like I’m failing.
