How do you relax?

So I’ve passed my due date and had an appointment with a lovely midwife who told me that stress and adrenaline often stops people going into labour. Once we relax, our brain signals our body that baby can come out. She told me to just relax but as anyone with ADHD knows, relaxing is not relaxing 🤦🏻‍♀️ I’m not feeling stressed or nervous about labour, I’m just really really excited!!!! The more I try to just chill and do nothing, the more overstimulated I feel. Does anyone have a tips on how I can just calm down a bit. I’m so uncomfortable now and done with being pregnant!
