If you have a very stressful job, how do you switch off?

[NegativNancy]

Just that really. Won't list all the stresses I'm facing as I'm sure many of us are struggling at the moment.
I really struggle to switch off though. Most nights I chill on the sofa watching moronic videos on YouTube or unchallenging nonsense while sinking wine and waiting for my head to shut up. I really want to get out of this habit though for obvious reasons.
I just don't have any oomph or energy once I've got home and had dinner. Partner is kind, supportive and does more than his fair share of housework.
I'm struggling hugely with sleep also. I wake up at approximately 3:30am and instantly click onto work. I have work conversations in my dreams and often email myself in the night.
My holidays start in three weeks but not sure I can keep this up for that long.
Any tips for switching off much appreciated.

Running, ideally outside. You don’t have to be good at it or fast (I’m neither). Couch to 5k is a good place to start if you never have and obviously currently we have lighter evenings

as well as reducing the stress levels it also really helps with sleep

I asked my boss how he switches off and he said he see his homelife at the weekend as a really important project that takes priority. Although he has is nailed on switching off.

How old are you?

I run, volunteer and socialise. I'm knackered and often don't feel like it but always feel better for going and having made arrangements with others forces me to leave work at a decent hour.

Once I'm out, it's a few hours I won't give work a thought.
