She'll have to find an outlet, and if it can't be healing, then she'll be forced to branch out in other directions.Both of those would run into the issue that her power, while it might not like healing all of the time, will not really be happy with almost never healing anything. It's worrisome to think how that might manifest... which makes it all the more interesting to see where the story is going to go with it, because it makes it almost a certainty that hiding things and playing it safe isn't going to work in the long run.
