Never thought I'd ever be this mad at my MIL

So, the other night, my MIL has the nerve to tell me that I need to clean my place because if it were inspected, child protective services would take my baby away... my place is not that bad! Yes, there's a pile of laundry that needs to be done (our dryer is broken) and yes, I have a couple loads of dishes in the sinks, my dining room table is cluttery and my upstairs bathroom that the baby doesn't even go in is a disaster, and sometimes I forget to do the dumb litter box and it stinks, but the area that my baby is always in and his nursery are nearly spotless. I would understand if I had knives all over the place and molding food or something... and I realize that I haven't finished cleaning and baby proofing the house yet and I plan to. (He's only 5 months and only recently even started rolling over) But I honestly think my MIL was way out of line to even say that to me. I have PPD and anxiety issues and she knows this. Am I wrong to be totally pissed off at her right now?? Like I don't even want to talk to her or let her see the baby until she apologizes.
