I agree and endorse all the wise and well-worded responses above. I think that everyone on this thread has given you, CocoE, some excellent advice.
It's a pity that you say (rather abruptly) that you don't want any tales of positive outcomes - this does seem to suggest that you were seeking people to agree and legitimise your thinking re: terminating your pregnancy.
I think this is perhaps further supported by the fact that since you posted seeking advice you haven't responded to any of the mountains of reassuring advice that has been offered - was it perhaps not the kind of response you were wanting?
I think (in the nicest possible way) that you need to have a good examination of your motivations behind your anxiety, your thoughts of termination, and perhaps most significantly, the responses you wished to (but didnt) receive on this thread.
Finally, and in contravention of your rules on responses, I really must let you know that you won't have done any harm at all to what was, at the time of drinking, no more than a blastocyst (a microscopic collection of cells floating free of you and separate to your bloodstream and any alcohol in it). I have worked with alcoholic mothers and mothers on crack cocaine - some had babies on the FAS spectrum, others had healthy babies...You are NOT one of those young women. You have no need whatsoever to pursue this line of worry, so please try and take heart. I'm 5 months pregnant with my first, and despite having witnessed the horrors of FAS first-hand at work as a substance misuse worker, Im happy to say that I can get it in proportion and so I'm not scared about the several binges I had before I knew I was pg at 8 weeks, and I'm thoroughly enjoying the occasional glass of mulled wine (and can't wait til my xmas day glass of fizz).
I really hope you can find some peace and relaxation this christmas.
