Family history is definitely something to think about! I don't think there is an easy answer to how you could not drink and not feel like you are missing out if that is what everyone is doing every time they go out! Maybe try surrounding yourself with people that like to do things sober as much as they do drinking, that way you have a balanced life of going out a appropriate amount and doing other things instead of drinking. Also if quitting is something that you would want to do, it's probably a good idea to remove as much of it as possible from your life, it just makes it easier to do.
