Sorry but didn't like it
The concept itself was ok but you presented it very poorly. The sound was terrible, it was boring and drawn out. I don't see how this could bring out any kind of saddness in someone, it looks like an animation short you'd find on barney or something. And I think the dialog actually killed it, you don't have to sit there and explain whats shes feeling. Play with different ideas and ways of conveying her emotions without bluntly telling us everything and it will have more of an impact. Work on your drawing alittle more too, the simple same thickness lines almost put me to sleep.
