Cadet is correct when he said that the "spacing out" is part of the depression. Have you read the thread called "In Tandem--MLC and Depression"? It's got a lot of good info on it and there is a second part to it as well. I'm going to post the link for the first part just in case you've not read it.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
