My drug addiction was controlling my life, and I was in a free fall heading towards rock bottom. The only path I could see was to keep using and hope for the best. That’s when I learned of another path, getting help and starting treatment. I’m now 3 years sober and have never been happier. The light is at the end of the tunnel, reach for it.
