Postpartum anxiety as a dad - is this real or am I being dramatic?

Our second kid just turned 2 weeks old. I've been having constant intrusive thoughts about something bad happening to him - falling, drowning, getting sick, whatever. I can't sleep even when the baby is sleeping because my brain won't stop. Wife has postpartum depression (we got her help immediately) but I didn't think this was something dads could get? Google isn't helping, it's all about moms. Should I just wait it out or actually talk to someone?
