Nina, So sorry to hear about your sister in laws. I know what you are going thru, when my mother passed away, one brother didn't want anything to do with the rest of us. Maybe someday things will change. My brother and I go to breakfast once a week now. Our sister passed on the 22 of August, his wife the 24 of August and my husband on the 1st of September all in 2016.
My oldest son had a stroke on tuesday, thankfully hie wife is an RN so she knew what to do, and took him to the ER. They transfered him to U of Iowa, the MRI showed he did have a stroke. He came home on Wednesday night and has to wear a heart moniter for 30 days. He had triple by pass 4 years ago.
My prayers are with you and hubby at this time.
