One time when I was younger I wore a Halloween costume that I'd been looking forward to show off.  But I ended up covering myself up with a cape, because I was self conscious of how I looked.
Well the costume itself ended up looking great, since my mom made it.  But I hadn't realized how fat I looked when i wore it, so I felt bad.
That's true, but no matter how much I tell myself that I always end up thinking about it too much about it.  I'm constantly worrying about what people think of me.
