"i wasn't enough for you"

It's been a hard week.

still jammin to this

Over those hills

I bet you're somewhere dreaming

walls

 

“Building up walls” is a metaphor for emotionally putting up barriers to keep oneself from getting hurt and to keep others at arms length. In this case, she compares her estranged lovers supposed “walls” to the entire “house” she has metaphorically built up in order to say her defenses stand stronger. Perhaps through the trials in this relationship she feels as if she’s been forced to build up an impenetrable “house” to protect her emotions. (via source)
