What's wrong?

Oh, I'm just tired, that's all.
Tired of feeling like I'm not good enough,
Tired of trying and not getting any credit,
Tired of feeling like I'm getting nowhere,
Tired of getting put down,
Tired of being left behind,
Tired of being given up on,
Tired of feeling like I'm waiting around for things that will never happen,
Tired of being disappointed,
Tired of caring too much,
Tired of insecurities,
Tired of being unconfident,
Tired of being tired.
I'm just tired, that's all...
