You need a few more commas to break up your sentences a bit, and partition into paragraphs more. From a subject matter point, you’re clearly aiming for high emotion, but you have to give the reader a little more connection to the main character first – i felt more attached to the mother, which i don’t think you intended to do.
I’m glad the mother has returned and is trying. Now, you should give the girl more in her life to worry about than just her twisted emotions surrounding her mother. :)
