Oh Chris, you sound so down hen, listen to what everyone is saying, we aren't just saying it to be nice but because we care about you. You will not look like a chunk, yes you are heavier at the minute than you would like to be but you are still a gorgeous woman inside and out and you deserve to have a lovely trip away. If you get sore, rest, if you eat un-dukan enjoy it and then when you get home re-focus. And, the only people that matter are the people that know you and love you. Big big hugs xxx
