My mother's birthday is Oct 2, I have had one without her, and it stunk. But I did what she and I loved to do, which was garden.
I wish she were here to do it with me, but that is something that makes me feel closer and connected to her.
If there was something your mom loved that you love to do too. Maybe do that. Yes, it won't be the same without her. But maybe it'll draw you just a bit more connected.
Thanksgiving almost exactly the same as Katie. Hard the first year, actually a little harder the second.
Christmas, the first Christmas, I did it because Mom would have killed me if I didn't and it was hard. THis year was easier, but I still missed her intensely.
