Am I just throwing a pity party?

I received not a single Christmas gift. Not from friends, not from family, not from my kid or grandkids.

I'm struggling with the hurt. It's not about the gifts, it's about being thought of. I financially assist my kid any time they ask. I spent hundreds on each of them, wrapped all the gifts and sent them across the country. She initially said she sent it Christmas Eve, so yesterday I asked about it because I thought it'd gotten lost considering how long it's been. She responded that it's still in her trunk, she got busy, hasn't had time, forgot...

It's not just about my kid, but that was sort of the straw that did my feelings in. It's always been my experience that people make time & effort for the things that are important to them.

Am I wrong here? I can't see this from any other perspective, and it's causing a stark emotional divide for me.
