Oh Poor you-I really do sympathise, this has happened twice in my life,once when I was 17,my hair as straight as pump water and the hairdresser cut it so short I looked like a boy,I was so embarassed,

I would not go to college for a couple of weeks!!and secondly about 16 yrs ago, I asked for a bob and came out in a style replica to that of a German Helmet. Worse still, a neighbour who I barely knew,asked me what I said to upset the hairdresser so much. Again very very embarassed.

Still as you say,at least it grows back. My present hairdresser who I have been with for seven years knows EXACTLY which length to go. I'll even let her experiment with different styles,just so long as they are no shorter than my desired length.

Cheer up,everyday that goes by it will get longer.
