Abbey will be fine. Sure, she'll miss the 2017 year, but she's incredibly talented and will find her fitness again. 2018 will be a good rebuilding year, as she won't have to worry about making a team. Remember, this is the girl who was third at NCAA 5k as a freshman after never breaking a 5 minute mile in high school, only running 20ish mile weeks. That is sheer talent. Plus, she's bounced back well from injuries in the past, none as serious as this obviously, but once she's cleared to cross train, she'll be able to stay in good general aerobic fitness.
Good luck Abbey! Can't wait to see what you can do when you're past this.
