I think the subject of the song is her depression, and she is talking to it, as she says "cause I don't know what I've done to deserve you and I don't know what I'll do without you" like she doesnt know what she did to deserve all of her sadness, but shes had it so long that she doesnt know if she can live without it, she "wants a reason to repair", or "a reason to be there", basically she wants to have a reason to be happy, because right now she is kind of ok with her sadness, as shown by this line "I can't see nothing good and nothing is so bad", but she also doesnt want to be ok with her sadness, she wishes she cared enough to change it, and she cant explain what she means because she feels all alone, and like no one would really care, good song i must say
