I'm so sorry to hear about your mother. I lost my father last November. It does get easier to accept the loss as time goes on, but it is a very hard time. There has not been a day since his passing that I've not thought of him, not only once or twice during the day, but numerous times during the day. We live on the other side of my parents double house. We saw him everyday. The start of the warm season was especially hard, because he did a garden and loved to grill. I found myself sitting out in the backyard wondering how we'd get through, but we did. The holiday's were very hard too, he was a very big person on family get togethers...get togethers for any occasion.
My dad had numerous health problems, including type 2 diabetes, high blood pressure, clogging of the arteries, heart problems. He was in NY to have a procedure done to open the main artery to his heart. It was blocked 90%. They started the procedure, and minutes into the procedure, his artery collapes, and he went in to cardiac arrest. Which in itself is bad, but he had a difibulator, and it was shocking him because of his heart stopping due to the cardiac arrest. The doctors could only stand and wait for that to stop because you are not able to touch someone that has their difibulator going off because of getting shocked themselves. Once that stopped, they started with trying to revive him, but to no avail. Only my mother, one sister, and one brother were with him in NY, we live in PA. They put him on life support to help with the beating of his heart, and when they tried to take him off of it, his heart would not restart on its own, then his kidneys failed, then his liver. They could not save him. They kept him on the lif support until the rest of us drove to NY to be with him. (my parents had 6 kids, all of us but one are married, each with 2 kids) We all drove the 3 1/2-4 hours to get to be with our dad for the last few hours of his life. It was very very traumatic, something we didn't expect, because he had these procedures before, just not on the main artery to his heart. We saw a double rainbow on the way to NY, we thought, that's a good sign. It was of sorts, not for us, but for him, for now, he would not be living in anymore pain or suffereing with his medical problems anymore. He would be at peace. I still miss him so very much, but know I will see him again some day.
The support of family and friends is extremely important. Lean on them when you need to....for anything you need them for. My thoughts and prayers are with you.
