Lstew, prayers for your sis and family! Maybe this is the wake up call she needed to get her problems under control. So glad you could be there for them.
We had a family emergency too... Hubby's youngest brother in Baton Rouge LA passed out on the floor, no telling how long before his sister found him. He went to the ER by ambulance. They did testing that night and the next morning he was in surgery. He had a large tumor in his brain, and also a clot that ruptured (causing the collapse). We are waiting to hear if this tumor is benign or cancerous. If it's cancer, he has to go back into surgery. They are keeping him sedated, but today he was taken off the respirator and put on a machine that only assists breathing--he starts the breath. We are praying for the best possible outcome.
Their father (my hubby's stepfather) also had a big brain tumor back in the 90's, and once they removed it, it grew back! They had to take it out again, but he died within a few years. So maybe these brain tumors are hereditary?
