I glanced through the comments, so not sure if this had been asked. Have you had any major changes happen in your life? A new situation that can add more stress & depression can make it difficult to focus. I had treatment for stage 4 uterine cancer. I'm now in maintenance. I've noticed more & more I have trouble keeping my attention on much of anything. If I'm fortunate, I might get 15 mins before my mind wanders. Posting is a struggle these days. It takes longer to gather my thoughts. Is it reading or other things you've noticed trouble with as well? I'm used to having a strong, sharp mind, so it's concerning. I have an appt on Wed. I'll mention it then. I hope you find out what is causing this & are able to find ways to manage.
