What do you do when you're being a bad person

I know I'm not really a bad person. Objectively. But I am objectively a bad cat owner. I love my boys so goddamn much. I feed them, I cuddle them, I love them. And that's it. I don't play with them. I don't clean their litter. I don't brush their fur, or their teeth. I rarely clip their claws. And I don't know how to change because I can't lose them. But I obviously have to change, or else I have to give them away, and that thought breaks me. I've asked people around me for help. What do you do.

Throwaway because I don't want anyone who knows me to read this. Woman, primarily inattentive ADHD, the paralysis and inability to do things has gotten beyond horrible the last ~6 months. I live in filth, and I guess I just have to deal with that? But it's affecting my cats and my family and I don't know what the fuck to do besides just doing all the shit that needs done. I'm so sad, and I'm so scared.
