Fortysomething, you sound very low. As nearly50 suggested, you sound as if you do not enjoy your job. Is that the problem? Spending so many hours doing something you do not enjoy will drag you down. Your situation does not help you to flourish.
You need to work to pay the bills and to contribute to your pension, but this doesn't mean you don't have choices. How many years have you got to work till you retire? What kind of work would you really like to do? Is there any possibility of changing jobs, sideways move where you work or retraining?
Who are you doing all the household cores for? From your post, you sound as if you are on your own. Are there household tasks you could do less often? Who's the judge and jury on what's done or not done? (I've had to let go on preconceived standards (tendency towards OCD) around the home due to health issues. It's really quite liberating!)
Your main responsibility is to yourself! Making time to do the 'me' things, the things you enjoy, the self care things. That's far more important than housework! Looking after yourself. Going for walks, smelling the roses! You have time away from work. Who's stopping you doing these things? What would you like to do in your free time? Do these things and fit the housework around that.
I remember my Mum finding the age of 63 difficult to get through, particularly as all her family died young, but she got through it. She'll be 90 later this year! My sister died at age 50. I turned this around and did the things I had said I would do...one day, while I could. My one day had come. I went travelling cheaply. I didn't wait for perfect circumstances. I'm so glad I did, as I couldn't go now.
Have some fun! Make a list of what you would love to do, but don't dismiss any for financial or practical reasons. Big and small dreams! Take your time. Without restrictions you will find out eventutually what you really want. Then is the time to consider the how.
