My Secret Santa skipped me while I went out of my way to make sure everyone else got included.

Today we had our holiday work party. I knew there was a chance that a couple people might not be able to make it so I grabbed a couple extra gifts to make sure everyone was included. So I get there, we chit chat and eat then do gifts. Sure enough our boss was unable to make it so I grabbed one of the extra gifts for my co worker so she didn't go home empty handed. After everyone else has gotten their gift I hear my coworker say my name and then she says "I'll get you something eventually." Oh. I see. Of course I said it was fine, no worries but honestly it hurt. There were so many options for what she could have done and she did nothing. And unfortunately she has proven over the time we've worked together that she doesn't follow through.
This has been the worst year of my life. My mom passed away from breast cancer in February and my dad passed unexpectedly a week before my birthday in October. But I still show up for others. I feel greedy or something being upset about this but I was really looking forward to the gift exchange. 🤷🏻‍♀️
