to me, it sounds like this guy has serious self concious-type issues and he's envious of this woman's life. in the first few lines he's in so much pain that his reality is messed up and she's almost telling him to just get over it. he feels like he's getting old now and he hasnt lived his life as well as she has, and now life seems like complete crap. when he says "you fall away and then you starve" it sounds like he has an eating disorder or BDD, especially since he can't get over these awful feelings. behind all of the darker lyrics, he's saying that he's going to make himself feel better by "gracefully dancing", which is something that he can do without worrying about envy, or getting old, or feeling awful about life. it probably makes him feel better about life actually, since its the only thing left that he can enjoy.
