Love Isn't Always Happiness

My mom told me about love, but she never told me everything. I found out more, though.
It's someone being your whole world.
It's when you care about a person way more than you do yourself.
It's when a simple "hey" makes you smile ear to ear.
It's when you have been together for months, & still get butterflies in your stomach and your heart still races.
It's when they finally leave (because they always do), and you're losing nights of sleep, and screaming their name, asking, "God, why?!"
It's the burning in your chest.
It's when you shut everyone out, because you don't want to talk to anyone but him.
It's when you think you can move on, and you try, but cry because it doesn't feel right.
It's when you can still smell what they smelt like after they leave you.
It's when you can still feel the texture of their hand against yours.
It's when you can still feel their arms wrapped around you.
It's not always happiness.
