How to stop overthinking

Anyone else randomly fixate on something and completely over think it? I do it all the time. My most recent over thinking was taking my little one trick or treating last night along with her 10 year old bro and his friends. So the boys ran ahead of us and the dad I was with went after them while we took our 3 year old door to door. The other dad messaged me to let me know where they were and rather than bringing my three year old down the street the long way to where the older kids were we took a short cut thru ally ways. Now I’m kicking myself for not going the long way and taking my 3 year old to more houses. Honestly I have no idea why all of a sudden this has popped into my mind and is bothering me so much. My 3 year old got more than enough houses in and had a blast regardless. Seriously how do you stop your brain from over thinking so much. Like I can’t stop thinking I made a poor choice by taking shortcuts and missing a ton of houses 🤦‍♀️
