Addiction is not a sign of weakness or lack of willpower; addiction is a progressive psychological (and sometimes physiological) condition. It may have developed recently or slowly over years. It may be possible to identify some reasons either from the past or more recently that have resulted in you using alcohol/substances, people or behaviours to change the way you feel. Perhaps there are things happening around you currently from which you want to escape? Maybe it has become the only thing you can do to feel as though you can manage?
