Are you sure you aren't just making it complicated? [Maybe he got turned down by a girl or something...] I mean, look. If you're going to put yourself down before anyone even says anything, it's kind of a self-fulfilling prophecy, you know?

I bet even a debbie-downer like you has some good points. And if you're gonna work on that self-esteem of yours... maybe you should ask people what your strengths are instead! It'll give you something nicer to fixate on.
