I read it and didnt quite get it. But i reread it and Understood. This is an excellent poem and you are an excellent write.

[Holding heart-shaped balloons tightly in her hands.]

that line really helped me to picture her loneliness and longing for love. It's like, she wants it, but these symbols of love, (heartshaped balloons) are the closest she gets to feeling it right now. That's so amazing!
