Anyone else's anxiety spike when kids go back to school?

Every August my anxiety goes through the roof. I know it's irrational but I start worrying about everything - are they making friends, will they get bullied, am I setting them up for failure, what if something happens at school that I can't control. My therapist says this is normal dad stuff but man it's exhausting. Anyone else deal with this? Looking for tips on how to manage it without spiraling.
