I'm frustrated at my birthday dinner
Why are you frustrated at your birthday dinner?
Getting older sucks. Being the only adult in the group makes me stressed to be the "responsible one".
Maybe you can focus on friends and family and leave the worries about responsibility for another time. It might make the evening more enjoyable.
It is too late to change. I'm frustrated now even though it sucks I will have to put up with the awkward dinner.
Many people have to celebrate their birthday alone, but it's okay not to. You can always make plans at another time to celebrate your birthday with other adults. For this dinner, try to focus on how good it tastes and and find ways to enjoy the company.
