I think you handled the subject matter well. It wasn't completely sad, but you also acknowledged that it's going to be difficult in the future, both for Michelle and her mum for having to watch her being in pain.
I'm not so sure how I feel about the structure. It felt a bit fragmented, but not done for effect. It would have been nice to see some more scenes with their interactions, and maybe interactions with other people too. Although, at the same time, I do like that it focuses on Michelle and her mum; it gives the sense that they have a strong bond. I like the use of the 'Once in a blue moon' saying too.
I had to default the layout because of the font you used though. It's difficult to read on certain browsers.
