@mercuryash It can be consuming. I know you want to vent but my heart goes out to you and i wish to share some tips in case it helps.
When my son was that age we kept a membership to the local children's museum. It was less than $100 for a year for one kid plus one adult. We only went on weekends but in your case you could make use of something like that after preschool or on days off. It was a little boring for me but it was a good way to get out. Besides a museum, there might be free library programs, Facebook groups, park ranger programs, etc where you can get out to take the edge off and have different things to stimulate and entertain your child. Then, after being out, she can have some downtime at home (like tv) to rest and without you feeling guilty.
I often took my son to short hikes and gardens since I like being outside. Then the big wide world entertained him but I had to keep him safe. When playing inside at home, if I needed to play with him a bit then I might put on an earbud and listen to an audiobook, and just go along with whatever my son was playing or doing. That was more entertaining for me, and sometimes I could learn things. Not every moment has to consome you and be cherished by you anf be perfect. Try to entertain yourself too.
I often let my son make a mess at the table with playdoh or drawing/crafts or building sets. Even if he only did that a half hour, and I have to clean it up, it gave us time to do things separately while still together. Then we practice cleaning up together and it's only 5 minutes to clean up. It's worth it.
