You are gallium Yttrium. You are loved. You are cared for. People would miss you. People notice when you don't talk or aren't at school. There's probably a person that you've only shared a few words with, or a friend you naturally faded from that misses you when your gone, randomly thinks about you, reads something and thinks if you would like it. You will always be loved more than you know. You wouldn't make the sky anymore beautiful, you would make those who care look up at it and cry every time, seeing at as something of sorrow, something that stole you away.
