So sorry this is happening. You have a lot on your plate.
Was your mom's childhood a good one. I've seen this cycle before where grandmother to mother to Daughter... They all treated their kids in a poor way.
If it's the case , I'm So glad you see it and understand it. I've read how much you love your Son :-)
Hopefully your aunt can take over.
