I think song is about someone who feels lost, probably boarding on a breakdown (january clipped your wires) because they tried to be perfect and meet everyone else's needs(sign that passed you, used to point towards you). So, they are finally left vulnerable to others (stones fallen, wall around you). But they still have their dignity despite being an almost wreck. (i'm not scared to go home).
