BAD FRIENDSHIPS

I have friends who steal, they use drugs, they are bad influence and in some way they have dragged me into their vices, like cigarettes and drinks, I being shown months ago as an example to other people about how they should behave, I feel that I failed people who have always had a good impression of me, like my mom, my grandmother, people who would never believe that if someone were to tell them, I feel that I failed to convert myself into what I criticized, leaving aside my true friends who saw me grow and train as a person and simply gave way to stupid temptations, luckily I could realize in time before having bigger problems, I think you might need some guidance and I would really appreciate it.
