No brainpower after work

How does everyone manage to get things done outside of work? I (26F, currently taking concerta) work a regular 9-5 and I have no issues there and am generally very productive, but anything that my brain classifies as not work-related is immediately disregarded as being unimportant. I miss bills, forget to respond to texts/emails, struggle immensely with the laundry and the dishes, and generally feel like shit outside of work. It's like 100% of my mental battery is used up by my job and I'm left with nothing for myself. How can I cope better?
