Life's a lot like swimming. At first it's really overwhelming when you don't know what you're doing, but you jump in anyway because you have a lot of people around you that you trust to save you if need be.

Then you get used to the water, and get used to everything. Doesn't seem so bad.

Then, all of the sudden, when no one is watching you start drowning. You're alone, and you struggle to take that breath. But there's no one there to save you. And all you have to rely on is yourself.
