I have been forced to make little notes on everything if I expect to know what I did 5 minutes from now or even 30 seconds for that matter.
I won't bore you with everything, but I was where you are now not too long ago. Someone very wise here at NT helped me realize that we can know longer expect to be able to just barrel our way through things like we use to. Try not to be hard on yourself. But like kitty suggested, try make adjustments like making notes, to make your life go smoother for you.
Before I even knew I had ms, in my 20's I started have to tape sticky notes around the strap of my purse if I was going to remember to do things when I got home from work that I thought of during the work day. It made my life so much easier when I just accepted it and found ways to cope.
I wish you so much comfort and hope things ease up for you!!!!!!!
