What you have to keep in mind is that you can only help someone if they want to be helped. Sometimes people need to play the victim and its a vicious cycle. Wether its an attention getting scheme or a defense mechanism, you can only help to a point. Yes, its aggravating and its hard seeing your friends hurt themselves but at some point you have to realize that youve said your piece and let them deal with it on their own.
You can lead a horse to water, but you cant make it drink.
