Memory Issues

I (26f) have been an EA supporting a VP in the retail sector for 2 years now. 4 months out of that time I was out on maternity leave, and my daughter is now 17 months. I acquired a new VP about 4 months ago. His pace and way of working is much different from my last and very demanding, and I never feel like I can get ahead. Lately, I feel like my brain is failing me. I cannot remember simple details without having my email or notes to aid me. I don’t know what to do about it and it’s frankly embarrassing. Has anyone else dealt with this? I guess I am just looking for solace.

Thanks
