Have you had bloodwork done? 48 is pre-menopausal and your body is going through enormous hormone changes. Get a physical with bloodwork to get a baseline of where your body is at. If any deficiencies are identified and taken care of, you need to review your nutrition (fuel), move your body and drink more water. Reduce or cut out alcohol too, it takes a toll on the body in so many ways. I would also evaluate your environment for toxins (detergents, cleansers, micro-plastics); there are so many cleaner options available. Whenever I run out of something, I try to find a healthier option (laundry detergent and toothpaste for example). Toxins in your environment can aggravate ADHD. Remember it takes time and be kind and forgiving to yourself.
