Congrats, I know the same exact feeling.

When I proposed to my wife, I bought the engagement ring online, and had it shipped. I followed the shipment, and was at work when it was delivered. As soon as I saw that, my heart jumped in my throat and I couldn't eat for the rest of the day. I went home and proposed to her that night, because I didn't think I'd be able to take having it in my possession any longer.
