Echoing what everyone else said. Get that thing fixed, and get yourself back on the trails. There will probably be a lengthy recover period. If I were in that situation, I'd probably want it done sooner rather than later, and heal over the winter. Good luck Mandy, it will all work out.
Take Charge. Train Harder. Suck Less. No Excuses.
It's good to hear that you finally have a diagnosis and a plan. Good luck and I hope you have a smooth recovery.
