I think that this is fairly interesting. I also think it's pretty accurate. I know that my own perceptions on life, problems, events, people, etc, are much more 'realistic' (at least in my terms) after experiencing lows of depression, however mild. It gives you time to live in the frame of mind of somebody who's depressed, but still realistic and optimistic (most of the time, at least). From this, I could sense that you'd get a reality check. Depression is often associated with loneliness, amongst other things, and isolation from others at times. Most browsing here can relate, and understand that time to think isn't always a good thing, and that time isn't always a healer.
On the plus side, from this, we do gain a strong outlook on life. An outlook that gives us the ability to look on the bright and not so bright sides of life, and think more realistically towards life events. I thought everybody would be like this, but not everybody is. Hardships really do sculpt people.
