great song, im confused about it thought, what point of view is the song from? the person thats on drugs(medicine) or a friend, he says go gave someone else im far too gone, but then in another part he says stop this your scaring me and who are you sometimes as if a friend is takin the drugs or is he just talkin to himself?
