The only thing that will heal your pain is time. It will take a long time, but you will be ok. This is the thing about life; it sucks when the ones we love die. And, then we will die, and make others sad. I wish we could live forever, and make the World a better place. All the wise ones die at some point, and we have to try to carry on their legacy in a troubled World. Take care. Safe travel back to MD.
I am very sorry reading about the loss of your Mother. I don't care how old a person is when they lose their Mother, it's very hard. Hugs to you and your family.
