Being left behind is one of the most painful things I ever experience. All my life people have walked out on me. All my life I have never complained. But now I want nothing more than to scream. Just start yelling at the top of my lungs until they completely collapse. Scream until my throat feels like it's being ripped to shreds. I don't want to be abandoned anymore. Sometimes it feels like people only know I exist when they look right at me, only to fade back out of existence when they look away.
