For what it's worth, I believe that often all we need to do with our emotions is feel them. And cry, or laugh, depending on the emotion. You have suffered a tremendous loss, like a bereavement. After such a grave loss, it takes a while just to feel like you're able to tread water, never mind on the road to recovery - especially when the one you've lost is the very person you would have relied on to get you through it. I've been through this myself. As a result, i had to relocate to a new country with 2 kids in tow, find a job, get a house, support them and myself... "Keeping busy" for sure! It keeps you moving forwards.
I second what Lane said about you being great to have around this place, and I bet you are doing a fabulous job of renovating that old house.
