Heal?

It was some tv spot trying to raise awareness for Depression. The parting line stated that Depression is curable. They said I could be healed, so why do I not believe them. It is truly odd because I have often said that I believe that there is a way to be relieved of Depression. I don't know what it is or when it will come but somewhere, deep down I believe it. So when I saw this ad it puzzled me that my first instinctual reaction was to doubt it. It's like I have these two very conflicting internal responses. One full of hope, the other full of fear. It is not a pleasant mix.

So what do I make of this?
