I did the same thing around your age...


Firstly, I couldn't keep watching the train wrecks, it was heart breaking.


Secondly, I thought it was stupid and selfish of them and I wanted no more part in their infantile decisions.


Thirdly, it was simply time to grow up, and move forward. Sometimes that means letting go.


Over the years some of my friends have cleaned up their acts and we have managed to rebuild our friendships, for others it was either too late to salvage the friendship, or they never bothered to change their ways.


I see no wrong doing on your part and no reason to feel guilty. You're doing what's good and healthy for you. Nobody else is going to do so for you, personal responsibility is a positive thing.
