Lyric discussion by AnotherBrick 

This one pretty much explains itself:

It's about someone who pretends to not have a care in the world, but is actually suffering on the inside for whatever reason.

"Stay with me my angel I found you Now I don't feel low All of the rest will flow"

This is the part where the person has found something to makes him happy again and as long as he does not lose it he can withstand anything that threatens him.
