The fear I get...

I have no problems liking someone. But sometimes when I do, It's always because I get worried that they'll like my sister or a small friend I have- me and my friend only talk at school. I always get that fear. My sister is a year older and pretty and actually has guts to talk to people. My friend is the same, and she's just more punk than me.
I'm shy, I don't have guts to talk to people, I'm lazy sometimes, I'm weird- which in my opinion is good-I'm clumsy...yeah. But my sister is prefect. Who wouldn't like her?
I don't think I'm jealous...I don't know. I'm not perfect...so I get worried.
