     The day my boyfriend fell to his death,it started to snow,just like any November day,just like the

bottom hadn't fallen out of my world when he freefell off the roof. His body. when I found it,was lightly

covered with snow. It snowed almost every day for the next four months,while I sat on the couch and

watched it pile up. One morning,I shuffled downstairs and was surprised to see a snowplow clearing

my driveway and the bent back of a woman shoveling(铲)my walk. I dropped to my knees,crawled

through the living room. and back upstairs so those good people would not see me. I was embarrassed.

My first thought was, how would I ever repay them? I didn't have the strength to brush my hair let alone

shovel someone's walk.

     Before Jon's death,I took pride in the fact that I rarely asked for help or favors. I defined myself by

my competence and independence. So who was I if I was no longer capable and busy?How could I

respect myself if all I did was sit on the couch every day and watch the snow fall?

     Learning how to receive the love and support that came my way wash't easy. Friends cooked for

me and 1 cried because I eouldn't even help them set the table. "I'm not usually this lazy," I wept. Finally,

my friend Kathy sat down with me and said,"Mary,cooking for you is not a chore. I love you and I want

to do it. It makes me feel good to be able to do something for you. "

     Over and over,I heard similar emotions from the people who supported me during those dark days.

One very wise man told me,"You are not doing nothing. Being fully open to your sorrow may be the

hardest work you will ever do. "

     I am not the person I once wfls,but in many ways I have changed for the better. The fabric of my life

is now woven with gratitude and humility. I have been surprised to. learn that there is incredible freedom

that comes from facing one's worst fear and walking away whole. I believe there is strength in surrender.
