AITA for arguing with my mother after she brings up something she swore not to bring up

I am a person with a lot of mental disorders (autism, add, ADHD, PTSD, and depression) who lives with a mother who has the most of the same mental disorders (but she has OCD as well). We have had many arguments in the past that usually begin the same way. She tells me to do something, I start to do it, she tells me to do something else, I start thatwhich leads me to forget my first task, she checks if the first thing is done and gets angry. It all started when she got a skin condition one day from an old apartment we lived in, it has never left us and bothers us to this day. (If you need more information let me know, so back on why I made the post) I had woken up after being asleep for two days, the first thing she asked me to do was transfer something into the dryer and take a bath, so I do that. When I am done and go to ask her what else I can do, she tells me why I did this (while she is holding up a "dirty" towel). I asked what did I do, and she tells me that I know what I did (not cleaning the dryer). I asked her when I did that and she said a week ago. We go back and forth which made me angry enough to yell at her about how she never said anything while we were both working just three days prior. So am I the asshole? Would love to know what you guys think
