How do you show 'your' grief?

A couple of Saturdays ago I decided to trim the yard with a weed-whacker. As I was pushing in the plug I did not realise that I also had my fingers on the start button so when the plug was completely in the stupid thing went to work as it was suppose to. The wire attacked my feet and shins and I did the maniac dance. My husband tried to help but I needed to find that place of calm for myself. Once I was pain free I went back to work but I was in too close a proximity to my husband and began to shower him with dirt and stones. He was not at all pleased and in response I threw the weed-whacker on the ground and went crying into the bathroom. My tears were so intense and so out of proportion to the silly event that just happened. As I sat there on the toilet seat weeping into toilet tissues I asked myself what on earth was going on. I realized that I was releasing the grief that I had buried and ignored. The was a lady at work who was dying and her husband never left her side. When I asked how he was doing, he said "it is not about me, it is all about her." I explained that we cared for the whole family and he was grateful. He still did not leave her side and he only slept for two hours at a time. His love for her was so magnified in those last days and I could not deny the grief. Once I acknowledged my own sadness I could release the pain. I went on and defeated the weed-whacker and the yard.
