<human>: Background: I'm a DJ (as my username suggests) and was spinning at a club in the city. After my set, I come out and start walking to my car which is parked a few blocks from the club.

Suddenly, a friend who I haven't seen in ages (since school), runs up to me and starts screaming hysterically - this is at about 3:30am. She is absolutely incoherent and is making no sense whatsoever and starts screaming/crying/freaking out all at the same time. I don't do drugs, but I've seen enough people on them through my job, so it was obvious that she was on something. She is an attractive girl who was dressed up for clubbing, but was hanging out with this group of seedy/creepy looking thugs outside a strip club, who were trying to take advantage of her.

So, essentially, because she had no friends around (I tried calling everyone that she knew from my phone, including her parents - nobody answered), I couldn't just leave her there, drugged out of her mind on the side of the street in the middle of the night. I couldn't live with myself if she got attacked or raped or worse and I knew that I could have helped her. So I take her to my car and we go back to my place and I set her up on the couch to sleep. I also made sure to leave water/hand towels next to her and a note saying where she was if she woke up and started panicking. 

In the morning, I hear her get up and go out to see her, and she starts laying into me. She can't believe how sick and perverted I was for taking her back to my house and she thought I took advantage of her etc etc. Pretty much calls me a "fucking psycho" and leaves without any sign of gratitude at all when I practically saved her from a potentially dangerous situation.

Turns out (after speaking with her friend) that she had taken 2.5 ecstasy pills AND some flu medication.....and the cab she took from my house, she jumped out of and didn't pay the fare (aka taxi gapsi).

Can you summarize the given text in a few sentences?
<bot>: Found a friend in the city tripping balls on drugs who could have been raped, took her back to my house to sleep on my couch, didn't get any thanks at all.
