It's not bleak, one thing you can't buy is time. I stopped working four and a half years ago. I have a modest income, approximate to you and for 3 years lived on that . This year I decided to start taking my pension, still got 8 years until my state pension, calculated id need to live unit I was 85 to break even on not taking my pension now. So id rather have the money now and use it for extra holidays as im fit and healthy now but who knows when im 86 what ill be wanting, but doubt ill need as much money.
I have on average 8 weeks away a year on holiday, varies different types and prices of holidays.
I quit the gym and my car is old, I have savings, but those have actually increased since I stopped working. I don't go without but like op I don't want stuff. I have done some major works on my house, new garden just before I stopped work and new utility. Then 2 years ago a new bathroom. I have enough money for a new to me car, but will keep the car I have until it needs to be changed.
There is much more to life than working 9-5 or 6-3 and I didn't want to be tied to a regular pattern any longer.
I fill my days with doing what I want to do, meeting friends, going on day trips, volunteering, hobbies take up a lot of time and family. The most important thing is being there for family and I have been needed for more than one member and a very dear friend.
I don't miss work and I certainly enjoy my freedom, I wouldn't have worked any longer for more money either. I'm satisfied with what I have
