She's grown distance between her and the rest of the world...
She wasn't like this before. She was the type of fun girl, that would light up a room and add life just by walking. She was one of those joy providers, those ones you'd smile just by passing by in a hallway. She was all about friends and relations and deep interactions... always ready to communicate, to connect, to have a deep conversation, to share burdens, to offer help, to laugh irrationally, to try to figure a sense for existence...
But then she had it, her heart break... She stepped to live life to the fullest, the same way she always suggested to everyone and she got smashed to the ground...
It was paralyzing to all of her senses. The amount of pain.. and yet she couldn't admit it, she couldn't cry it out, she couldn't... She managed to keep a smile and still face to handle the roughness of days... but with time, she started backing off from all aspects of life.
She found peace in isolation. She found rescue in solitude. It provided her balance she's been lacking for a while.
