Super Insecure

Me,being myself,is always on my own. I do not care that much if people didnt know me, I mean, I dont even know everyone.
Some of my friends,are doing so well for themselves, being busy with the student's society and such. And I,sometimes I feel like I never really move. I just stay there. Quietly.
I'm not the over-friendly type. I dont like to open up to people. Sometimes they  just dont understand.
I do LOVE my friends. They complete my life. I just dont like being too close to someone, I'm afraid they will leave me one day.
