I don't know that I would even follow my own advice but I do honestly believe that coming clean would be the best possible solution. But, as you already know, the consequences will then be forced to be dealt with. And if you're not ready for it then - i'd advise you find the best possible way to cope or manage. Because addressing just one area and having multiple other undisclosed or areas can not be beneficial - as one could be exacerbating the other, etc.

In whatever you decide to do - good luck! You have a big decision to make either way! Very scary stuff...
