AITAH for being hurt my friend is doing the same bday party theme as me?

I’m celebrating a milestone birthday this year. My bday is on Christmas, so it’s always complicated to plan bday parties, especially as an adult. I have done two small bday celebrations in the last 15 years. This year I decided to do a big party. It’s an RIP to my youth theme. I know it’s not unique, but I’ve put in a lot of time planning, getting decor, making the invites, etc. invites were sent out 5 weeks before the party.

I just received an invite for a close friend. She is invited to my party, which is next weekend. We both celebrate the same milestone bday within 30 days of each other. She is having the same theme, he invites very similar, the look, the content, the section about a “eulogies” and “wearing all black,” all of it is the same.

Our good mutual friend is helping both of us with planning. Neither of them mentioned the shared bday theme to me. This friend also does huge bday celebrations every year, multi day events. This feels so dumb to be upset about, but it does hurt my feelings. My birthday is already overshadowed by a major holiday, now my friend is doing the same theme. Would you be upset?
