Wow. As a fellow mental health professional, I could not disagree more with your post. Depression manifests in many ways, and it seems strange that you would so easily diagnose based on his Internet activity. After all, there could be a manic element to his struggles.
Either way, I'm surprised at the level of butt hurt this seems to generate with people, like Nate has personally wronged them or something because he dropped the ball on a comic book.
I agree that his internet activity doesn't paint him in the best light, but I don't think any of us have enough info to diagnose or judge him. Hopefully he gets the help he needs.
