sorry I was just commenting on your user name for the site "lethalinjection" Please don't think about it and lets' go one to other topics on this post that are more to point about drilling, oil & gas, etc
I think most of us have no idea what "real" clinical depression is like.
I think clinical depression can be a "brain chemical" thing instead of an "emotional" thing.
It's sort of like the difference between, "I'm feeling silly" vs. "I just drank 6 beers." Sometimes those who get hit by depression have no more control over themselves then someone who got slipped a drink with alcohol in it.
Luckily, I haven't experienced clinical depression myself. (yet)
