We are forced to believe that we aren't enough for those around us, we are forced to believe that we have to be completely happy, completely perfect for others to even want us. Nobody is completely perfect? Ask the woman who can't have kids of her own. Ask the men who wake up screaming over world war nightmares. Ask the teenage girl who is drinking until death do her part. Ask the teenage boy who's covered in his father's scars?
No one is completely perfect, nobody is perfect.
