I did it too...alcoholism can lead to behavior which resembles it...but I don't think we are qualified to make such decisions, especially about somebody so close to us. It's presumptuous, assuming a level of competence to diagnose someone so close to us...and us being non-professionals in the psychology dept... I did it too...!
It takes the focus off the things we can control, once again, we need to stop it when we start going down that path...it has no purpose, and put the focus back on ourselves and what we need to do, our goals, our unfinished business. I realize now it was sick, mentally unwell, to do that test for someone else. I had no business taking someone else's inventory.
