If dad is suffering and immediate family calls, I would think someone would give you some kind of info. Therefore I'm assuming this can be translated as: "I called the hospital sounding like an insane garbled whiny junkie and they weren't having any of my bullshit."
Luna wasted the time she could have spent with her dad and any opportunity to clean up crashing at his place. Junk is a waste of time and life. The world kept going by while you were high, and now your dad is in the hospital, idiot.
It wouldn't surprise me if her dad is on drugs too, but doesn't it seem a bit too on-the-nose that RIGHT when Luna is "getting sober" (on benzos) her dad is also having some big medical crisis and totally might die but also needs physical therapy (and is on benzos?)
Eta: agree it sounds like a stroke. Again, not defending dad (the whole family sounds like a mess) but I just don't buy her stories off the bat. She's "so scared u guise" and has no idea what's going on, but also knows exactly what drugs he's on and how much? Sounds sus
