My gut would be to tell you to support yourself and support your sons and be there and be open if she comes to you for help or support given her health situation. Even then I'd be strong and try not to be weepy. Maybe affirmation if she needs it like 'we will get you through this'.

I could be all wrong though. My thoughts are with you.
