It has been my experience that active alcoholism can mimic any number of mental illnesses.
I truly believe that a person cannot be accurately assessed until they have been sober for at least 90 days. Alcohol causes brain changes and brain damage. Heck addiction is a mental illness in and of itself. I mean, how many come on here and say they have depression and anxiety....only to sober up for a time and say, hey, I feel much better?
Get and stay sober. See what happens.
