UPDATE:
She was wasted. Ended up spending most of the night in front of the toilet. I was worried SICK. Never seen her this way before.
She apologized profusely the next day, and I accepted it, but reminded her that I do get worried about her and that she needs to pay more attention to her phone
She's fine now. I had to drive us to breakfast that morning because she was starving and nearly passing out. Part of her problem was that she barely ate the day she drank, which explains why she was so intoxicated by 4 cosmos.
So everything is fine.
