Sad to hear that.. Just be strong for your parents. Wishing for their fast recovery.
As we became older where we can start to stand on our own.. that's the time we can return the favor to our parents for taking care of us.
This is our obligation to them and to show our gratitude and respect for bringing us to this world.

Really glad knowing someone like you who loved their parents so much!
You are a good kind loving son...
