I am so sorry about your diagnosis. I know that each day we are all a day closer to our inevitable death. Most of us blindly believe death will be at a super old age. When my grandmother was in her 90s and had limited mobility, she felt useless. We constantly told her that her job was to pray for her family, even the children yet to be born. Her prayers still impact our family. We knew she prayed for us. You can continue to impact your family and our world even with mobility issues.
