Alone at Christmas - am I expecting too much?

My closest and oldest friend knows I’m spending Christmas and new year alone and won’t see anyone. She also knows I have COVID, so couldn’t go out even if I was well enough. Last year was my first Christmas completely alone, due to bereavements, and she knows I found it difficult. She’s celebrating with family as usual, which is lovely, but is it too much to have hoped for a quick phone call at some point? She’s found time to post on social media about the great time she’s having, but not even to ask how I am.

A number of things are making me re-evaluate this relationship now, but am I being unfair, or reasonable? I’m trying to work that out. I know how I’d respond if she was alone and unwell over Christmas. Any thoughts would be much appreciated!
