AIO for how my sister asked me to babysit again?

i work overnights. she knows this. i've watched her two 8 times since january, always on my sleep. this was tuesday. i said no for the first time and i've felt sick about it since.
What People Are Saying
the last line is why i've felt sick for a week. she knew exactly where to put that.
"I'll ask mom, she'll be thrilled to hear you said no" is a threat wearing a normal sentence's clothes
you offered saturday. you didn't refuse to help, you refused to help at the specific time that endangers you. those are different and she flattened them.
eight times since january on no sleep. she's not asking for help, she's got a system and you're a load-bearing part of it.
Should I stay in my house, move downtown, or move near my daughter in Ohio?
my 7yo now demands a full salute before he'll eat his cereal, thoughts?
Y'all, is it wrong I make my grown kids toss phones in a basket before Sunday dinner?!
Should Bill and I go to our son's in Denver, our daughter's in Austin, or just stay put for Christma

you fell asleep at a light. i work nights too and i need you to hear how serious that is. this is not a favor question anymore, it's a safety one.
