I think this song is about someone who is looking at themselves in a mirror and trying to convince themselves that they are not the person they see in the mirror. For example, he may have been abused or had a hard childhood, and this person convinced themselves that they would never be like there father or mother, but looking in the mirror they are realizing that is what they have become.
It seems to be a constant fight with this person and they could be trying to talk themselves out of suicide.
