I liked your piece and I think it sounds like it's going to be a very interesting story. So far I like your character, it seems like she's had a rough childhood and is now forced to live with a not very nice "un official" adoptive mother. You left me wondering why she got hit and why she was ungrateful, which was good because it's always a good idea to leave a bit of mystery to later be told.
I think your work needs a read through to patch up some things that you could maybe make sound a lot better, or just fix some points that don't really make sense. You can never check and read your work too much, its good for your writing and good for you readers and most importantly improvement.
A downfall is that this chapter is very short and could possibly not be considered as a chapter. It is still very good, but I think you could have made it a lot more longer, like carrying it on from when she blacked out. Say like a few hours later, or the next day, just in the same chapter as again its very short.
Overall I really like this and would be interested in reading more. So if you do post up more, let me know I'd love to read it and review it for you
I hope I've helped and encouraged you,
