Anyone else get weird anxiety when their kid goes to school?

Started about six months ago. My daughter gets on the bus and suddenly I'm convinced something bad is going to happen. I check my phone constantly. Wife says I'm being irrational but the fear feels so real. I'm not like this with anything else just school drop off. Been thinking about talking to someone but also wondering if I'm just being a paranoid parent. Does this happen to anyone else or am I losing it?
