No words. Our hearts are with you. As DrJC said above, her spirit lives on within you and the other people she so positively affected. Turn to other loved ones and live life to the fullest.
My sister, on a long hike, was with her husband who died of a sudden heart attack. She couldn't turn him over to apply CPR and had no cell phone coverage. She had to hike back, many miles, to get coverage and then had to wait several hours as EMT came and recovered the body. An unspeakably horrible day. Today, near 70, she takes several long bike excursions including a river cruise in Germany that stopped every morning to let them off with the bikes with a map to meet the boat upriver that afternoon. This spring, she is going on a tour of Italy with friends. It takes time; mourn, grieve and be patient with yourself.
