Lost Son in law need help w/ eulogy

My son in law was sick for the past year in and out of the hospital with diabetes complications. My daughter sacrficed her life for him to make sure he had everything (that is what a wife does) He died suddenly during a routine surgery the other day. She did not get a chance to say good bye and it is tearing her up. Need help with a euolgoy & to mention my daughter as the person / rock that she was.
Thanks

Maybe the funeral is over by now so I hope you found some lovely words to say.
This site contains many poems and readings normally used at weddings but I often use 'love' poems at funerals where there has been a deep and abiding love. Acknowleging that love can fit very well into a eulogy.
