I've had a few alone Thanksgivings. One happened in my late 20's due to work. I couldn't get out of town. A coworker invited me to her house for that Thanksgiving. I was going to go, but I was so exhausted from work that I fell asleep.
Another time in my 40's I was going to to travel to family and became ill, so I didn't make it out of town.
When I lost my job in my mid-50's, I don't think I wanted to travel home because I was depressed. I ended up eating at an Old Country Buffet in Puyallup, Wa that is now closed. I wasn't particularly happy about being there, but at least I had turkey.
I can't make it this year either. I have mixed feelings about it. On one hand I'm not happy. On the other hand, all the adults there are partnered except for my widowed mother -and she's the family matriarch-and my sister who has a bf (although he'll probably be with his family) but has two adult daughters to bond with. I love my siblings. But we aren't pals. So I'm basically the only adult there who has never been married and never even had a relationship. It didn't bother me when I was younger. But the older I get the more alone it makes me feel.
