Praying for you sweet friend. I know the feeling about not being able to concentrate. As for passwords, I got an address book and put mine in it. Easy to find in case I lose them on password manager. I am dealing with tingling and numbness in both arms and legs from t.he stenosis in my neck. Arms and hands are worse. Praying you get your blood sugar under control and that will help you. Keep us posted. Love you.
