Hi my name is Anna. I got into cocaine and later heroin when I got into the club scene. My friends and I had a great time in our late teens and 20's. However things took a turn for the worse after I was not the cute young girl in the club anymore. I decided I did not want to be defined by drugs or the clubs. I have been living for Jesus ever since. Sharing my struggle and my glory which is revealed in him.
