I am not a fan of Mothers Day either. Starting when my two children were 10 and 12, they began to show they disliked me. At church (on Mothers Day) when they gave out flowers, the children were supposed to go up get a flower and present it to their mother. Starting that day,they refused to go up and get a flower. My heart was crushed. The next two years it was the same. After that I would no longer go to church on Mothers Day. It never got better after that.
I also am not a fan of Mothers Day because my own dear mother passed away almost three and a half years ago.
It is too painful of a holiday for me. I try not to think about it.
