Well, I think that last one was very cute. I believe that it was describing ones love for a cherished child hood sleeping toy, such as a teddy bear.

So much better than a boy,
You'll never leave me.
Follow me around,
Like a shadow on the ground,
Always watching over me,
Hanging over like a cloud,
Darkness slowly covers me,
Wrapping like a shroud.
Gripping the corners of my mind,
Creeping up all the time,
Tearing me apart,
Depression seems so much better,
When you have a broken heart.
