I think the fact you worry your attitude is damaging to your daughter , and you are posting about it on here means you do care about her.
Plenty of kids aren't dressed, showered and fed everyday.
Think about it, if you really just didn't care/like her at all, it wouldn't bother you.
So as PPs have suggested, make time for counselling even if you try some online counselling first and I also wondered can you check with your local community centre/council for groups and things to take her to when it's not daycare day? It'll give you somewhere to go where someone else is responsible for the stimulation and play and you can sit at the back and take a breath.
You'll probably find other mothers there who need a break too.
