She is a introvert , she feels uncomfortable around others, she likes to be alone in her small dark world..
she was not always like this once she used to think many relations and people will keep her happy, but they broke her trust, when she wanted to talk there was no one for her, there was a time when she expected some importance for her..
But what they did they left her alone just because they thought she was a child, she didn't understand anything but they were wrong yes she was a child but she understood many things that was new and harsh for here and it was the time she just wanted your care, your hug..
Now she likes to be alone with herself, now she is protecting herself from them to have expectations and trust on you..
she is afraid what if one day anyone will come close to her that much where she will completely depend on them and will leave her alone with their reasons..
They are complaining her to come out, they are complaining her to not talk to them but what about her...
No one want to be introvert but sometimes to protect yourself you have to keep your heart close......
