Grief has changed my face

I've finished reading "State of Paradise", Laura van den Berg's latest novel, and something struck with me.
In the book - to be precise, it is not so much a novel, as maybe a work of autofiction or speculative fiction - she talks about the physical effects of a recent pandemic on people's bodies. Weird belly buttons, changing eye colors etc. It is about how trauma can change your body and especially how you and others perceive it.

My mom died in January at age 57. People told me that as time goes by, things start to get better.
I don't know, for me pain has just started to feel incredibly real. At first, I think I was trying to cope with the "newness" of the situation. Trying to understand how I felt it, how my dad and my sibling felt it.

Now, the fact that what happened is irrevocably real, it just hit me.

Everyday I stumble upon a new detail in this new world I'm living in, a world where she is not here, and it gets more painful. I look at my face, now six months later, and I realized how much it changed.

I had a work event a couple of days ago, and I got all dressed up, I wore a nice lipstick, I did my hair. I took a picture of myself to send it to my friends and I realized how different my eyes looked. They just look puffier, more downturned - a completely different shape.

It's a weird post (also English is not my first language), but I was wondering if any of you had experienced something similar. Is it how I perceive myself or is physical change real when you're grieving?
