I just moved out over a month ago and boy was it tough at first. I think tell our D (who is almost 3 years) was tougher on us than it was on her probably because of her age. The key is telling her you both will always love her no matter what and that you are still a family but except she will have two homes.
I promise you your pain will ease a bit as time goes by if you do your homework. I'm no expert but I will share what I've done in the last month:
I'm starting to spend a lot more time on this board and it's given me a sense of community even though it's online. This board has helped me the most so far. Keep reading and posting!
Also, I'm trying to journal each day. I have 3 journals, Regular, Angry, Grateful.
Finally, I used a guided meditation to fight anxiety before and after I see my WW/STBXW. (you can download scribd on your smartphone and get the healing guided meditation audio book. It's about 15mins and it does wonders)
I initially thought that meditation and journalling was a bunch of hokey poky until I tried it and saw instant results.
Hope that maybe it will help you.
