Know how you feel Maggie. I can't fit into any of my summer clothes this year! I had a back op in May and then wasn't allowed to do anything for 6 weeks, literally nothing! I wasn't even allowed to hang the washing out. I ended up over doing it (walked too much as it was all I could do) and ended up in bed for a week with back pain (thought I'd buggered the op up). I was running right up until Easter so my shape was pretty good, now I just look terrible can't even look in the mirror! Bought a second hand cross trainer yesterday as it is low impact so hoping with that and lots of water and the right food I can start to get back on track. It's hard getting out of this frame of mind tho. Good luck with it all but dont let it ruin your holiday, forget it, have a great time and concetrate on getting back on track when your home :)
