I wanted to find out more about your H's depression. How long has he had it? What were the symptoms? I know about the A but how and when did that start? Did he use other forms of escape? My H also happens to be an alcoholic.
EAs and PAs are very common in the depressed. A great book to read about what may be going through the minds of the depressed is "Depression Fallout" by Anne Sheffield. It's an essential read for the loved-ones of the depressed.
