It seems to me that this feeling of disconnection is an issue in and of itself, one that could be dealt with on a deeper level than just eating a diet similar to the people around you. Disconnecting from people didn't stop you from going vegetarian, vegan, or raw, even though each one represents another degree of separation from the majority of people. You yourself said that socializing can actually be improved when there isn't a meal in the way on
day 14. Perhaps you could use this as an opportunity to connect with your family on a deeper level than what you put in your mouth. I think that this feeling of loss is probably more important than the juice-feasting itself at this point, and shouldn't be ignored by simply returning to your usual routine.
