Band of Horses - Funeral Lyrics Meaning

Well, as I see this song, it´s like, mmm let´s say I don´t have a very good relationship with my mother, so when I lisen to this song, it's like, fuck it, fuck you, I mean, everybody says stuff like ''Oh, you have to stay with your people, your family, they ain´t forever, you know?' And it´s like, ok, fine, but man, you don´t know anything, family it´s not somenthing you choose, you could be born with a family that doesn´t give a shit on you. So, I think my interpretation it´s that, I don´t care bout´you, I don´t give a shit, you can die, I won´t care. I won´t regret, you hurt me so much, and ''coming up only to show you´re wrong'' cuz' I won´t cry for you.
