Anxiety about what I’m forgetting to do

Hi, I am currently staying at home with my 3 small children and trying to maintain a schedule while also doing some work from home. Lately, I have had a lot of anxiety because my thoughts get interrupted frequently by my little ones and I often get sidetracked mid-task. Whenever I have a small amount of time to myself , I feel so overwhelmed and anxious because I feel like I have a lot of things to do (ie. emails for work and school, making activities and projects to keep the kids busy, maintaining the house) but often can’t think of what needs to be done in that moment. Sometimes, there probably isn’t even anything pressing but I just have the feeling like I should be doing something and can’t figure out what it is. Often, the feeling is paralyzing and it makes my thinking even cloudier. I’d love some more productive ways to handle this. Here is the thought model I came up with for my current thoughts:

C- my day with 3 children at home
T- There’s something I’m forgetting to do.
F- anxiety, overwhelm
A- inaction
F- I end up frustrated for not using my time more wisely and it makes it harder for me to enjoy this time with my kids because I feel so distracted.
