The film touches on a lot of issues concerning disability, but does very little with each of them before jumping to the next one. And then, towards the second half, the movie changes direction to focus on Yuma's complicated family history rather than her personal struggles; it feels as a contrived pretext to not really answer the questions of the first half about love and sex, but just say "she reconciled with her mom, so everything is fine".
Annoyingly, most of the conflict in the film is resolved by the fact that Yuma is a very talented artist, kind of wealthy, pretty, kind, and well-adjusted to be independent. So the moment she makes some good friends, it seems like all her troubles disappear. It's one of those cases where the story looks as if it's centered around social issues, but in reality it's more about the character dealing with mental barriers, and once those are overcome the film forgets about all the systemic problems which are still there.
And then, the friends she gets sort of fall out of the sky, and immediately decide to take care of her for no apparent reason; they are the nicest, most supportive, and least judgemental people in the world. So again, the film takes the easy way out and avoids dealing with any of the problems people with disabilities encounter in more realistic, flawed friendships.
