Eloping after initially deciding on a larger Dw??

Hi all! I need some advice :/
My FH and I have been engaged since 2017, over the course of the years leading up to today we were planning a DW. It was originally supposed to be a small gathering with maybe 30 people and.. then the guest list ended up getting out of control. We sent out Save The Dates several months ago and after coming to the horrible conclusion that unless we wanted to be $20k in debt, we should probably change our course. My family has been difficult with me in terms of planning, I’m feeling way more overwhelmed and stressed out than I had thought I’d be. We came to a decision a few nights ago that we should just “elope” in our location of the DW with a max of 10 guests (I have elope in “” because I realize it’s more like an intimate ceremony).

What do I do now?? We have informed our guests on the website that we were holding off on the plans. Do I send them a more formal change so everyone knows it’s off? Will people not even really care? I never got to the formal invite part, just the STD’s were sent out.
I feel really horrible about all of this because we were just going to postpone the wedding (so we told our vendors that) and then my FH voiced that we shouldn’t keep waiting- we’ve been together for 8 years. And I agree with him! It’s been more stressful planning this huge thing when we’ve been together so long because it doesn’t feel that special and we’ve always been the kind of people that it’s just US. We are a 2 person team and we basically can only count on each other. (Sorry thats side tracking a little bit)... but now I’m reluctant to tell my vendors again that we change our minds once again! I feel like an idiot and I need help 😞 how do I deal with feeling like a fool? Lol.. this is what we want and we have both agreed that this is the plan and we aren’t changing it, (I am very indecisive and I also try WAY too hard to accommodate to everyone else).
