I often tell my 12 year old daughter not to fret over friends at a young age. Everyone is still learning and experiencing changes in their lives. When we are older, we can count our true friends on one hand. I had a similar experience. I am in my mid 40's, and I quit drinking a little over a year ago. I was helping myself to become a better person, friend, and father, but many of my "friends" I had several years ago have vanished. I guess I will make new friends and you will too!
