We all have to find what works for us when it comes to getting through the pain of loss. My way is my way. Yours is yours. I've used writing my entire life to work through difficult spots and to understand my life. I think its a tool that anyone can use. You don't have to show anyone your writing, you don't even have to save what you write. Or you can start a blog, write a letter, or keep a journal devoted to your grief. The simple act of writing down your deepest feelings has been proven to heal (check out the book: Opening Up: The Healing Power of Expressing Emotions by James W. Pennebaker, Ph.D, a research psychologist.) One of the reasons Widowed Village is so brilliantly helpful is the way in which it encourages us to write down our thoughts about losing our spouses in this shared environment.
For more ideas on using writing to heal, you might find my blog to be of help. In it, I list a number of exercises you can try, if you don't know where to start.
