I don't want to bring my mom to the er at 1am
Why not?
Because i'm lazy.
Lazy?  Too bad.  You need to take care of your family members when they're counting on you during a medical emergency.
If you actually cared you wouldn't be saying this. and fuck off, I'm going to sleep.
It sounds like this might be an emergency though. You should take her in if she needs it so that nothing worse happens to her.
