Welcome onetime - you're here talking about your problem and that's a great first step. When it comes to your friends, remember that you're doing this for YOU - so that you can have the best life possible.
When I was drinking I hung around other drinkers, so it wasn't too surprising that they didn't appreciate my sobriety. My social circle has expanded a lot since then and to my surprise, there's a whole world of people who aren't getting drunk several times a week (they actually have the energy to do something with their lives, too - and it's kinda inspiring to be around them).
Take it a day at a time and keep posting!
