Genuine OT help on a new engagee

We talked about the engagement for months and wanted a year- long engagement to plan.

I proposed on a trip to Hawaii, I caught her off guard at South Point on the big island after we both jumped off. We had discussed a year- long engagement for a long time, we had both talked about a Hawaii marriage a year after the proposal. I'm ready for that, I don't care where/ when, we made that clear beforehand. Now that it's real she's so overwhelmed with trying to plan anything she won't start with anything. I'm not pressuring her, I'm just listening. She's saying things like "I want the perfect dress and for everyone to be there and for my friends to help me with the dress, people keep asking about the date, it's too much." I keep telling her I don't care about the when and where, this is your wedding not theirs, the only thing that matters is that you say yes!I told her make a list of what's most important and start there; venue, dress, who can make it to the destination. Then, once you have the most important thing down, we'll work the budget from there!

She loves me to death, she's excited to pick out my ring, which idc about, but she's in one of those positions where there's 100 things to plan so she can't plan any one thing. One of my sisters even told her the dress was most important so she bought that and then planned the wedding in 3 months. I just feel like if she thinks she's helping herself by waiting because it's a destination wedding then venues are going to get booked up, and loved ones that you want there are going to pass.

I may clarify more if needed but even her friends agree that the first step should be picking a budget, or it can be picking a venue and date, or even just a dress. She's ecstatic every day to be engaged but keeps saying "I've never planned a wedding before, I don't know where to start" and I'm like "Neither have i, but we can start anywhere you like!" We're meant for each other but we had both agreed previously that we didn't want a 2-3+ year engagement and it's already tending towards that..

Any advice??

Tldr: love of my life is dragging her feet with all of our families now that she said yes. We're both committed but she's overwhelmed with the thought of planning a wedding, which I get by we have to start somewhere.
