I think this is your problem. If you believe you will never get out of the hole, you never will. If you want to get out and make efforts, you will start to see steps. I compare curing depression to walking up a gradual slope, you make each step and make progress, but you might not see the progress you're making at the time.

I think you should push yourself to do something new whether or not its appealing. Keep trying until you find something you enjoy. If you don't like books, you could do short stories. If you don't like reading, you could draw. If you don't like any of those things, maybe do some stumble upon, I don't really know what you should do, just have faith and stay awake and lively.
