You made a booking and then cancelled at the last minute, for no good reason, causing her to waste her time and possibly lose out on an actual booking. Don't do this, she had every right to be annoyed.
Not this annoyed though, and that's another important lesson - some prossies are crazy . That's the main reason for anonymous punting phones, and never inviting one to your home, and so forth. And your choice of which one to see was frankly barmy. But she's achieved her objective of scaring the crap out of you, this is probably over now.
My advice: take a break, calm down, get a punting phone, and try again with someone who has several good reviews on here and no mention of anything dodgy. Then decide if that experience was worth the risk - as there will always be some risk.
