Be happy that you have paid for it and it is a done deal. I made an agreement to purchase a bike recently on facebook marketplace but I was not going to be able to pick it up for 5 days. Like you I was obsessed with looking at it frequently wanting to get my hands on it. After a couple of days the seller marked it sold sending me into a mini panic. I had made a more than fair offer to him so he had marked the listing sold to curtail the inquiries from people wanting to know if it was still available.
