I am so very sorry to hear of this tragedy . I cannot imagine how deeply you must be grieving and suffering, and there are no words that can really take that away. As others have stated there is no way for us to be perfect and always anticipate every outcome. We've all let our guards down at some point, sometimes we realize it afterwards and sometimes not.

I know you are grieved beyond words at Jewel's passing, but know she is waiting for you at the Rainbow Bridge, healthy, whole, and happy. She loves you very much and awaits the day when she can joyfully greet you again.

My deepest sympathies go out to you, you will be in my prayers.
