when it comes to angst i think of the song "Anthem of the Angel" by Breaking Benjamin and especially the lines "there is nothing left of you, I can see it in your eyes" and "I keep holding on to to you, but I can't bring you back to life." though maybe this is just simply sad...
oh! that's one aspect of angsty sad stuff that i haven't thought about too much! i'll include something about it :')
