Work is definately an escape for alot of people.
A few individuals at my work when COVID hit it's first of many peaks/waves of March 2020, were forced to stop coming to the office.
They shutdown the office March 14, yet these people were still coming in March 31.
The reasons varried.
Children, family, environment, , lack of wfh infrastructure, personal challenges (one employee hit hard times and didn't have internet at home or mobile device, company hooked him up with mobile hot spot and mobile), and many more.
With my own personal home life challenges, working from home 3+ years now, I have sat in my home office "working" while I catchup on binge watching on days I am actually off (I work with clients in North America, i might work a stat holiday of one country, I might not, varies per holiday if they are on diff days -- I take of both Canada and USA thanksgivings).
I have a friend at work who sounds alot like your post.
The only exception is he doesn't have a family/responsibilities really.
Work is his hobby/life, shows up on his days off just to chit chat with friends at work(he does have friends outside of work).
We joke he would sleep there if he could.
You need a hobby, something productive to do outside of work :) something I am struggling a little myself with
