How do I stop overthinking literally everything

Title says it all. My brain doesn’t let me simply rest. I think about some stuff to the point of feeling like I have OCD.

I’m sure many people do this but if I’m traveling…I double check I have my wallet with my drivers license and other cards multiple times. If I’m traveling overseas..I check for my passport every hour. EVEN THOUGH I KNOW I HAVE IT.

If I use the stove or oven and am done cooking for the day and go to bed…I’ll lay there overthinking if I turned off the stove or overnight. Even though I know logically I would have noticed by then if I didn’t. I mean this is hours after cooking. I will still get up, go downstairs, and check.

Work is worse though. I work as a manufacturing engineer. ANYTHING I do in our facility I will quadruple check cause I just feel like somethings going to be wrong. Even though it rarely is. If I replace a tool? I will walk back to the tool multiple times to verify it’s the right one and it’s working properly. 2 nights ago, I laid it bed thinking about another work project and how something might be wrong so I got up, found my work laptop and once again triple checked. Again…I know everything is fine and is correct…I literally wouldn’t be able to fall asleep if I didn’t check. Because my work is so important I just can’t accept I did something right the first time…even though I know I did..

I have a ton of examples but the work ones the worst.

I’m just tired.
