How do you switch off from work?

How do you switcch off from work. I'm currently on holiday, took a week away with Wife and kids for the first time in 6 months. I'm present when we are doing stuff throughout the day, I love spending the time with them and I am enjoying the break.

But if I'm. Or doing something,(out, swimming, playing, cooking)my mind just goes to work. I love my job but I know this isn't healthy. Because of this, I'm never sat down, I'm always finding something to do. It's the same at home on evenings weekends tbh.

Its like I just don't know how to stop?has anyone else experienced this, what do you do to help?
