I watched you die
I heard you cry every night in your sleep
I was so young
You should have known better than to lean on me
You never thought of anyone else
You just saw your pain
And now I cry in the middle of the night
For the same damn thing
Shes talking about her parents divorce. I'm guessing that when they split up she went with her mom because dads normally take things better. What shes saying is that at a young age, she heard her parent that she was with crying every night, she watched them die. Not physically because I'm sure neither of her parents are dead. And now, shes older shes crying of the same thing. Either she went through a divorce of her own or shes crying because of her parents.
