Your daughter in law needs a reality check and your son should give it to her. NO ONE in your condition should be traveling for any long period of time due to the threat of a clot breaking lose and causing another stroke. Your son should talk to the priest and see if, due to your circumstances, a video could be make of the ceremony. If not, ask for pictures of your granddaughter in her communion gown. Send a nice card and an appropriate gift to your granddaughter. That is all that can be reasonable expected. You sound like a wonderful lady that has been dealt a bad hand medically. If your daughter in law is still being a pain in the butt, pray for patience for you, and understanding for her. Your son really needs to intervene here. I also suggest this website for you: www.strokenetwork.org. Best wishes to you and your family.
