I am so deeply sorry for your loss. We welcome you to the WhatNext network with open arms, and are ready to give you any support possible.
If/when you are ready, you can reach out and/or follow others who have lost a loved one to cancer. For example, check out CancerHAWK, http://whatnext.com/users/cancerhawk. She lost her husband to sarcoma and she has a great blog: http://cancerhawk.com/. She's a terrific resource and incredibly inspiring. There are several others as well, and I know the network will want to be there for you during this difficult time.
