to me it starts off in the 1st verse how things went from bad to worse. then in the 2nd verse talks about an abusive past. the chorus goes on to how as life went on things were bad, from cutting herself to running away from the problems. saying that she "better leave the light on" is saying that she needs to stay alive because of the "cause I wanna love i wanna live " quote. the last verse she says i swore to god id never be what ive become. and i think a lot of people have that issue. she also talks about happy things representing that she wants to change from hurting herself and getting hurt to good things and a happy life
