Is anxiety or depression something than can be overcome or just managed?

I have been visiting quite a few blogs, discussion boards and websites to see the overall consensus regarding overcoming or just managing anxiety and or depression. From what I have gathered the majority of discussion seems to be toward living a life where it can be managed. This in of itself is very depressing. If a choice exists to manage or be free from a condition, wouldn't the majority choose freedom?

So what are some thoughts, techniques, or philosophies that can lead to freedom? What is something you would share, something you would say "listen, you need to try this. You will be amazed at how this works"? What have been some complete failures?

Of the success stories I have come across there is one thing is similar, and that is consistency. They showed the determination and will to stay the course and in the end it seems they are now sharing their testimony with others.

My thought is to get enough people to talk and focus on what works, share success stories, and in the end live a life free of depression or anxiety.

Be well,
