oh hunny I feel for you. I think you're gorgeous no matter what but when I compare your FOTDs and these pics I say you're a much better hair stylist yourself!!!!!
I think she wanted to give you volume (hair stylists always assume you want huge hair, at least the ones I have encountered so far lol) but that didn't really work out.
Be glad that your hair is so healthy, I'm sure you can get it back to normal in no time. With long hair it's easier to "hide" a bad cut, although I don't think the cut itself is that bad (ok apart from the bangs) it's probably just the horrible blow drying job.
I've had stylists do bad blowdrying jobs on me, I just asked for STRAIGHT hair and she left me with a shapeless, frizzy mess that made my hair look completely damaged
