I have a lot of things but some songs I would mention:
-The song in my signature speaks to me personally. It's a song written by the band as a tribute to their old songwriter who killed himself, based on real events, and a confessing note he left. He killed himself by literally making a homemade guillotine, hence the title: the poet and the pendulum. But the words just convey how I feel so well.
-Next would be the song 'Eva' by the same band. It's the story of a girl who hates her life, and imagines herself sailing away, dreaming of a better place, and trying to convince herself that the real world is far away.
But the one song that gets me everytime is 'taking over me' by evanescence. It's how I imagine the girl of my dreams Is feeling right now, and I just cry endlessly over my longing for her to be in my life.
