I am pregnant now at about 9 weeks so there is about a week difference, but you feel guilty. Guilty to feel happy again. Guilty to feel excited again. But then when you get some sadness you feel guilty too for not being happy you have another chance.
It seems all the holidays brings these feelings, but they do seem to get easier with time. Less guilt and jist remembering.
So even if you are going through a tough time and it is the holidays it does get easier with time and don't feel bad to lean on family.
Enjoy your Holidays without guilt. Our children who have passed wouldn't want it any other way.
