Hi Pheadrus and welcome to the site. I can personally relate to a lot you have written in your post, and im sure a number of other members and guests will too. In the last few weeks, it has been quite shocking how many people have stumbled upon this site, and all have gone for years not thinking this was a problem as the PA eats and damages virtually everything good you have going in your life.
I am echoing what I say to most, and most will agree, taking the first step by acknowledging your problem is the biggest step you can make.
