Cover art for Unsteady lyrics by X Ambassadors

I think this song is about a family that is breaking apart as one and that is what is making him weaker and weaker as he say "I'm a little unsteady" plus this verse:

"Mama, come here Approach, appear Daddy, I'm alone 'Cause this house don't feel like home"

I think what that means is that this person in this case would be his mom, comes home and leaves which makes him feel empty as he also said "cause this house don't feel like home" because without his parents even being home, home isn't home.

It can completely be about something else but as stately cleary, he's talking to his mom and dad.

My Opinion

@mao1118868 definitely gives the impression of dysfunctional family, that perhaps is falling apart (divorce??)
