After a near death experience (years before cancer diagnosis) happening at the same time as my mom's death, I waited 8 months before moving across the state to a town where I knew no one. I'd lived in the same place for 48 years so it was a really big deal but it turned out to be the best thing I ever did for myself. Fun fact--I had a job in the new place but it folded within a couple of months and I had to make the decision to stay or go and I chose to STAY. Happy I did. To be honest, I probably would have moved sooner if I could have--but I think it is an individual decision. Susan
