I am now a widow

I have officially been a widow now 7 days. My husband, my best friend, my lover, my friend, my soulmate took his life last Tuesday. He leaves two children behind, our son who is 14 and our daughter, who is 10. I feel empty, flat, worthless. yes, I have lots and lots of support. But, I feel as though this is the worst diagnosis a person could get. Losing someone you love is far worse than any cancer I have ever encountered. I don't know how I will survive. I miss him every second of every single day.
