That is an incredibly amazing accomplishment. When you begin something destructive at a young age it can be very devastating to your life and even harder to quit later in life because it's already so ingrained. For that reason I am SO proud of you. I wouldn't consider myself addicted but I have abused substances quite a lot in my life to escape pain. Even if you find yourself struggling in urges again later on down the road, remember what kept you clean for so long. Expect fluctuations because no journey with addiction is only ups after the downs. I'm rooting for you!
