Depression is depression no matter how you got there. I recall the first time I was hospitalized was around 1987. Doctors were scrambling to discover what came first, my depression or my drug addition, which caused which? As if it mattered. It's a classic case of which came first the chicken or the egg. It doesn't matter. Each can breed the other! The result is the same. Need to treat both. In my case it was the depression came first. And it made no difference in my treatment whatsoever

No need to feel ashamed. We all fall for one reason or another.
