When is Enough, Enough?

Everyone has a different level of pain tolerance both physical and mental. My Uncle as an example, would have the cavities in his teeth filled with no Novocain when the Dentist drilled them.  Many on the other hand, would prefer to be knocked out and unconscious. The same tolerance levels to physical pain can be seen with mental pain also. It took me years to say I have had enough and had to fix my life. I finally “got it” that I could ‘not fix my addict. What did it take for you to say you had enough? Or, are you in fact on a path to self-destruction of yourself and your family because of your addict?
