I am so lost!!

I lost my husband on October 15th, and I am so lost! We were together for fifty years, and married for forty-nine. I was in shock for the first two weeks, and then I had work obligations which kept me busy until last week; now, it is like the reality has set in, and I cry off and on all day. I wake up to his side of the bed being empty, eating meals by myself, his chair vacant in our reading room, nobody to talk and laugh with during the day, and nobody to spend the evenings with. I have children, grandchildren, and great grandchildren close by, but I find myself just wanting to be alone if I can't have my husband. I don't like to leave the house anymore, and try to keep busy working around the property. Will I get stronger? Will I be able to get through this difficult time?
