not sure if you are getting hypo. always good to keep in mind, but you are just very into it, very dedicated, and doing very well i might add.
i seek comfort in food too in particular when i am down but i have known people who are more susceptible to that when they are anxious. it does sound like the prospect of meeting up with a bunch of folks made you anxious, but it is just an incident, a reaction, as i see it. i don't think it means much in the big picture.
now, if you don't usually do that, when anxious, then yes, it could be a sign that you are depriving yourself a bit much. if that is the case, then consider relaxing some of the diet rules a little.
