OP - you say you enjoy housework so maybe that’s the kind of area to look for work, places where you can put those domestic skills to use: cafes, schools, hospitals, care homes and private homes.
If you enjoys grocery shopping, what about a supermarket, picking and packing for online shopping orders? Or working in the bakery?
Do you like to garden? Several of my older neighbours have the same mature female gardener to help them out. She doesn’t do any heavy stuff, just cuts lawns and tidies borders. It’s a business but accounting must be straightforward.
Do you like to iron? A couple of male friends send their shirts out to be laundered and pressed. Again, another business that the woman runs from home.
Nowadays, you have to be a bit more creative about finding work. Agencies charge employers somewhere between 15% and 20% of the base salary to place people, so a lot of employers don’t use them. Nor will you necessarily see vacancies advertised in local papers, as used to be the case, as newspapers no longer have the reach that they used to.
It’s often worth making a direct - even speculative - approach to businesses to see what opportunities they have. You may just time it right and find that some seasonal vacancies are about to open up. For example, we have an independent garden centre here that supplies the most glorious hanging baskets for both the domestic market and local businesses. They offer a refill service, take along your own baskets. They take on seasonal labour. How do they advertise? They put an A-frame board out on the roadside! A temporary job like that may be just what you need to get your confidence back.
Any new employee has to learn the ropes but many service sector jobs only require common sense and a bit of basic training to get up to speed. Age shouldn’t be a disadvantage. In many cases the experience that comes with age is a great advantage.
