I handled Mother's Day this year by mostly avoiding Facebook and only going to church for the sacrament, then bolting out the door. I holed up at home, talked to my mom briefly, and made the aforementioned eggnog.
In the late afternoon, I was pleasantly surprised to have someone stop by with a bouquet from her garden. She's aware of my infertility struggles and struggled herself, so she understood. It was so sweet of her to think of me. It really helped.
