Look, it's good to know yourself. The probability of getting seriously messed by acid is extremely low, but the number one risk factor for a bad trip is being afraid of having a bad trip. Just don't worry about it and if someday you feel curious, just relax and do it. It sounds like you have a pretty good perspective.
Also, I will bet you that it wasn't (just) acid that fucked that girl up. Concerts are a great place to be exposed to all kinds of interesting substances.
I don't know. The first time I tried acid on my own I was quite afraid of having a bad trip. It turned out to be wonderful and transformative. My second solo trip I told myself something along the lines of "just don't worry" and it turned out pretty grim. A statement like "just relax" doesn't really compute cleanly and depends a lot on the subject's state of mind.
For me the number one factor was my external environment.

Wise advice. I've always been angry with people who pressure people into psychedelics. You must be comfortable and with people you can trust when doing these things for the first time. Not doing so can make for a damaging experience.
