my fiance and i had originally planned to get married this year (july 20, 2013) and we have had the church and reception booked for over a year now. in september my fiance had a very serious bad reaction to a hormone shot he was given by his doctor, it has set him into very depersonalized state, he is suffering from fogginess, dizziness, and very serious anxiety, it is hard for him to even leave the house sometimes because of the way he feels. due to his current health condition, we have decided to "move" our wedding to next year (july 19, 2014), however, all of our families and friends had already known about our date this year, we never sent save the dates, but just word of mouth and family talk. should we send something out saying we have changed our date so that people do not start making travel plans or anything like that, or do we just leave it go to word of mouth again? not sure what is the proper thing to do in a situation like this!
