Bree, first my condolences. I have lost two children and gone through an unwanted divorce. The one bit of advice I didn't read in the thread is this: be mentally prepared for setbacks. Although in general you will recover over time, there will be times when you seem to go backwards. These times may come at "obvious" times such as her birthday, or your anniversary, or they may just...well, happen for no obvious rhyme or reason. When they come, be kind and patient and accepting with/of yourself (and surround yourself with like-minded caring people) and just know that the road you're traveling is not a straight one.
I would also say that you may encounter people who will expect you to get over her sooner than it really takes. FWIW, it took me about five years to mostly get over the deaths of my children, and I think getting over my divorce will take about the same amount of time. Regardless of whether it takes you five months, five years, or some other amount of time, just take whatever time you need.
"At times the world can seem an unfriendly and sinister place, but believe us when we say there is much more good in it than bad. All you have to do is look hard enough, and what might seem to be a series of unfortunate events, may in fact be the first steps of a journey." Violet Baudelaire.
