I think that this song is probably about a guy who is sick of facing his demons like people pretending to be his friends when they're not and backstabbers and he's being driven way past his breaking point. Then on day he meets a person who although is also facing faceing his/her [though most probably her] own demons, he believes that she can help him through everything. And his 'saviour' was trying to help him but after a while she/he began having doubts. And he's singing for him/her not to give up and help him.
