Stressy-brain Problems?

Several times lately, I have been unable to find my pill splitter when it was sitting in plain sight on my bedside table. Yesterday, knowing this had happened before, I'd thought I'd looked on the nighstand carefully for it and couldn't find it. I got on the floor and looked for it in case the cat had knocked it down, but it wasn't there. I looked again on the nightstand and it was sitting right there. I don't know why I keep having this same problem.

Today, I made ramen for myself and I couldn't remember whether it's something I eat with a spoon or a fork. I stood there looking at it trying to remember what utensil I was supposed to use and finally asked Miriam.
I'm still having a lot of trouble concentrating on learning new things, too. I don't know what to make of this, but I don't like it.

A Facebook friend says it's stress. I hope she's right, and I hope it goes away when (if?) I ever have less stress in my life. Earlier today, I found myself lying on the couch while Miriam napped in the bedroom and just asking myself "Is this my life now?"
