Make a list of things you will need to do. Be detailed about it. Then, if you ever need the list, you will have it to guide you without doing any thinking which is hard to do during a stressful time. When my husband passed suddenly, I made a list but it was two days before I realized I hadn't included calling his sister! And, I concur, don't make any big changes for about a year. Grief is a form of temporary insanity (ask me how I know :)) and a person can find herself making all sorts of odd decisions.
