How can I find my house when I'm completely and utterly lost?

I went on a stupid fucking trip with my dog and I lost my house. I've gone into creative and flown around everywhere but I can't find it, and I just keep going in circles. My house is so easy to spot from a distance cause it's on top a giant hill with a ton of lights around it. I have no clue where it is. My spawnpoint is in the middle of nowhere so I can't reset to find it. I forgot what the coordinates are. I'm so lost omg 😭 I'm so pissed cause I spent months making that house. Is there a way to find it? Probably a stupid question but there's gotta be an easier way.
