Prayer Single View

I have been rejected by my children (adults). This disconnection is very hard to bear. It has been going on for many years. I am getting older and I am alone. Will the Lord please show me mercy and grant me some happiness? I need someone in my life who will love me, care about me, and share his life with me. I need someone to allow me to feel apart of someone else and not be alone indefinitely. The rejection of my children is worse because I am left out of my grand-children's lives too, which means I am not able to enjoy them as most grand-parents do. I feel left out of many peoples' lives and I am also jealous because of this unfairness. Please help me hold on to faith. I have lost much hope by now. Thank you to anyone.
