I’m 15, and wasted a year

Hey, I can’t believe that it took me this long to get back on track with my life. I relapsed almost two years ago and have gradually become addicted more and more. I’ve been clean before, I was almost a 2 years clean before I relapsed. But, ever since then my sense of purpose, drive, and discipline have all gone away and I know it’s because of my addiction. I’ve made efforts to stop over and over again but I just end up stuck again and again, a cycle. I suppose that this is my last hope to trying to rebuild my lifestyle back. I’d like for you to come forward with your journey and advice. Thanks .
