One of my group-mates last night described to me something he found very useful in dealing with his depression. He's a really smart guy, and a heck of a nice one, and highly articulate. I always value what he has to say and admire him for what he's had to fight. (SO much!) At one point he admitted himself into a hospital for depression; he really knows whereof he speaks. (Of course, so does anyone who suffers from it.)
He said that he realized that, in the absence of positive messages from his FOO and their involvement with him (they are indeed cold and isolated people), he developed his negative, depressive voices to keep him company. (His word.) He said these thoughts became a genuine companion to him; they filled the void left by his family and also explained them to him.
He realized that this wasn't much of a friend, told it so, and told it to go away.
He said this helped him to manage it quite well; that now he gets various moods/feelings, but it's never returned at that level since.
I wish I were as articulate as he. He explained it so much better. (Of course! It's "his.") The way he said it was very helpful. Passing it along in case anyone finds it valuable also.
