She has no-one who she could talk to.
No-one who could understand.
No-one who could help.
No-one who could listen without laughing and thinking that she's stupid.
No-one who would be there for her.

She's thinking that she's huge. She hates herself and her life.
Again, she wants to get out of here. She starts to think about what if she would die.
She's dieing inside.
She has started to loose hope. She's gone too far.
Let her go.
