A Piece or a Hole?

Okay, so maybe it wasn't such a miraculous recovery. I wouldn't say my depression is back, but it does peek in every once in while to remind me of how much it hurts. Does depression ever leave completely? Or is it that once you have it, it becomes part of you, and it will never go away...like a scar? I feel like I've been hurt so badly that I'll be crippled for the rest of my life. I shudder at the thought that I ever wanted to kill myself...that I was ever in that much pain. I can't forget what that felt like. I want to forget...I want to be able to live like it never happened. But I can't even imagine that. To me, wishing I could forget is like wishing I could fly. I feel like a bird that's had its wings clipped. Feathers grow back, don't they?
