Very nice story, but details would have made it better. How large was the bottle in terms of volumer? 500ml, 1L? What does abbie look like? Why hasn't she been to the bathroom in 3 days?
This could have been better, but it isn't terrible. Here are a few pointers I can give to you.
One, you should try to describe the character(s) you focus your story on. We don't even know what Abbie looks like, let alone much of anything about her.
Two, your paragraph structure. Your words are very cluttered and make it a bit tedious to read. There are a couple of spelling/grammar errors here and there, but everyone makes mistakes like this, so it isn't that big of a deal.
I do like your descriptions, though. They describe the situation well, and the details are attentive.
Overall, it's a good first attempt. I'm sure your next story (if you make another one) would be much better if you break it up into paragraphs, and pay a little more attention to character description.
