OCD and leaving for holiday

[Poppyliveshere]

Same struggle as I have every year but have 2 separate trips this year so worse for me. Build up to going makes me so tense, as I have so many what if thoughts about leaving the house. I have had OCD tendencies for many years, starting very suddenly in my teens. I go to work without any more than a quick check of rooms, taps, and locks etc, maybe takes 5 mins, but when going away overnight it becomes a totally different beast. Lots of prep with switching gas cylinders off outside, certain fuses for cooker etc off, and unplugging everything, plus multiple checks of doors etc. Takes ages to get off which DH tolerates but it’s quite tense. Any words of wisdom gratefully received

I really sympathise, I'm like this too!
I've stated making a list of all the things I worry about and then tick them off as they are checked. Long-suffering dh then does a confirmatory check for me and I take the list with me. That way when I get it into my head that I might have left the bathroom window I can refer to the list and see that’s the dh and I checked it before we left.

I take a video of the switches being off, or get long suffering dh to take responsibility for turning everything off. We also have a hive camera so could link to that to check the house was ok but I've not had to use that for a while...

The only thing that helps a little is my phone camera/video, as I record as I go, and usually end up deleting it after a few days, without ever looking at it for reassurance. It’s totally illogical, but it’s the build up and actually leaving I find hard. I’ve watched other people literally walking out, turning the key and not even giving the door a push to make sure it’s shut. I SO wish that was me 😩
