I'm sorry about your your grandma, but I'm glad your mom got to see her.
It's definitely a weird mix of feelings, isn't it? Disappointment, for me, in that I had nowhere to go, but coupled with relief and a feeling of freedom. If it adds any solidarity, I did not do anything either. My kids were out in Ohio with my ex-in-laws, I can't go to my parents, my friend who I usually can go visit for the weekend was away with family, and I just didn't try to call a lot of people to make plans, I just wasn't feeling like investing so much this year.
Instead, I cleaned my basement, did laundry, cleaned some of the kitchen, and watched a movie.
My Easter meal was a smoked tuna sandwich at 10pm. But at least the prep time was minimal!
