overused the ingenuity

What if I'm not who everyone wants me to be;
I'm not what anyone really wants.
Where is that fine line between being yours and not being a disappointment to someone; anyone.
Is this the source of rebellion?
Is it normal to be overcome by this fear that in pursuing who you really want to be, you're letting someone down.
I've become a Debbie Downer.

Sometimes I just get tired.
Its my fault; my own insecurities. I should know who I am. I should know how to say no.
I don't though.
And now I've overused the semicolon; it's lost its ingenuity.
