Not much to this one. I've had it said to me and I've said it to myself and my friends. Whenever someone experiences loss, failure, or heartbreak, that's what people say. It sounds harsh, but it's true. I never want to believe it was true; I don't think anyone does. But the sooner you accept that you can and will move on, if not now than in the future, the easier it is to let whatever it is go.
