Is it normal to feel lonely/solitude after being rejected by a crush?

A girl who I liked a lot rejected me and says that she has someone else. It's just a feeling that hits the heart and goes up to the throat. It's just like a feeling of missing out on something that you could've had and can't stop thinking about. Does anyone else feel this way after this happens to them?
