Writing can definitely be cathartic, and healing as well. My father passed when I was relatively young and writing in a journal helped me more than anything else. Of course blogs are essentially today's version of the good old pen and paper journal. I think it is a neat idea, and quite possibly could help another person to see that what they are experiencing is the same as what another is. It is strange how addiction and all the craziness that surrounds it can be SO SIMILAR amongst people experiencing it.
