My brain fog just cost me my job

I turn 45 this year. After being a SAM for years I had started working as admin support two month ago. Between my ADHD but I mostly blame my brain fog and basically lack of short term memory. I was let go today. Thankfully my husband is employed. But I am devastated, the two months were a genuine struggle. I guess I’m just here to vent and to maybe suggest if you are struggling at work with this maybe look for ways to help overcome this so it doesn’t happen to you.
