hey bob..
my name's rachel and i'm also young and sober. i'm having an equal amount of trouble finding other young and sober people. it's tough, but definitely (for the time being) finding things you enjoy doing would help - get passionate about something! it's easier to find people who you'll like who share some of the same interests and make that the focus of the friendship/relationship (ex. biking, other exercising, movies, music, politics, etc..)
everything has it's time. eventually you'll meet some like-minded people.
