Ok baliene firstly kudos on posting here in that moment. I know how hard it really really sucks being the only person not drinking in paradise. I spent most of my summer in a beach resort community every days a party. At first it was starting to break me I felt do angry and like you I knew I was not going to drink but didn't want to feel angry and left out. So whst I did was allow myself to get it all out all the sadness regret disillusion anger about not being "able" to drink. I cried I screamed I wrote. And you know whst it was gone almost. Take advantage of the early mornings when most will still be fast asleep. I would take my 40 oz of coffee and my cell phone and read SR on the beach!
You can do this and I promise you won't regret it and you will have authentic memories of good times! Hang in there
