You might be messed up, but everyone is, in their own ways. Your mess ups are your own. Influenced by your dad, but you aren't him.
And you can come back from your mess ups. You can live without fear. It'll go slow, and it'll hurt, but you can. It takes a while to heal from anything - getting shot, breaking your arm, your dad breaking your heart.
