Since she didn't actually do anything other than spike your drink, you're only assuming she wanted to make a move on you... Well, that's what you want us to believe anyway.
Here you go, this ought to clear things up related to your confusion.
So, the benefit of sympathy? You can see what they're going through and understand it, even if you don't quite feel it yourself. Lacking that means lacking understanding.

Huh, the difference between "I'm sorry" and "I apologize" links from that page. Hm.
I accidentally overdosed myself once. I snuck in some unregged benzodiazepine before my country rendered it illegal. I forgot what strength I bought and was too lazy to check. There was one 1 unit (don't remember how much or anything it was for real) and one that was 10. I assumed I got the 1 one which was much weaker. 1 unit was a max dosage so I took 2. Big deal, you know...
But in reality it was the stronger version and I had taken 20 times the max dosage. It took me weeks to get back to normal. Or what normal is for me.
