I've struggled more with sexual addiction issues with some possible underlying codependency issues, as is the case with many addictions.
I was in an inpatient facility from January-March 2010, and started seriously discerning the priesthood again almost immediately when I got home after getting a "poke."
Knowing full well all of my wanting-to-escape-reality issues, I decided to be more active in the discernment process. I needed to make sure that it was God and not another attempt to escape. I did get an overwhelming confirmation at Mass on June 26, and gradually started feeling drawn to monastic life as well. I've already filled out all of the application stuff for Mount Angel Abbey, but the vocations director said that I'm not a good candidate at this time, so my request won't even be put forward until the next application cycle.
In short, I don't think there's ever a right or wrong time for discernment. Rather, it's more about how active you need to be at this time in the process, which would depend on where you are in conquering your codependency.:)
