I can’t offer solutions, just reassurance that you’re not alone. I’ll put things down, turn away for a second, and forget what I did with it. I’ll walk into a room and forget why I went there, I will be walking around campus with friends and have to ask them where I am going or what day it is!
The only thing that helps is I have a 6 step checklist taped to my door so I never leave the house without my Keys, Wallet, Phone, (and the more ridiculous part) my backpack (yep, I forget my backpack when leaving for class), my glasses (I mean relay! I can’t see, that I can’t see), and my necklace that I ware to remind me that I took my meds.
Good luck all! Hope this helps somehow.
