Have you ever heard of a phantom limb? It's when someone loses an arm or leg, but they still experience sensations as if it's not gone. It's kind of like when you lose someone. You still remember their touch on your skin, and how their hand fit perfectly in yours. You remember how they smiled and how it lit up the whole room. You remember their voice and how the words that came out of their mouth were perfect and so them. You feel like they're still there. But when you realize they aren't, you experience the same agonizing pain and loss all over again.
