While it doesn't feel good Thomas, it's perfectly normal to feel as you do. "Feeling" our emotions is a foreign concept when were are drunk all the time so being sober lets all those feelings back through again - both the good and the bad.
Mindfulness is a practice that can help, as well as gratitude. It's difficult to practice at times but it really does help, and especially so over time. 14 days is a great run but you are still very, very raw and your mind is adjusting.
Regarding your vacation, you don't HAVE to go. Yes, others have expectations of us, but it's entirely up to us to decide what is best. If you feel that the pull to drink would be too strong, don't go. There will be lots more of them in the future.
