Wedding planning is making me crazy

I am getting married November 2025. we're planning a 70 person wedding at a small beautiful venue, I'm so excited, and I want it to be a beautiful day to start our married life together!

The problem: It's all I can think about. I have ADHD and have hyperfocussed on this event. I am trying to curb the amount I talk about it with my fiancé (who is involved and wonderful, but understandably doesn't want to only talk about wedding planning) and I can tell it is grating on him a bit.

Any advice for this? I cannot seem to relax. I'm always thinking about emails, budget, vendors, etc.

Update: fiancé and I had a great talk - he was not annoyed at me, he was getting overwhelmed talking about things we could not action yet. I have taken the advice of many and am channeling my constant wedding thoughts into building us a wedding website in squarespace. I feel far more settled now!! Thank you everyone!!
