Lost in Minecraft after resetting spawnpoint while exploring. How do I find my house?

So I decided to go out looking for a Woodlen Mansion with the Explorers map I got from a villager. I took a compass with me. My world was created on Survival.

The problem is without thinking I reset my spawn point with an extra bed I took with me so my compass always points to that area and when I die I get sent there so I'm stuck in the middle of nowhere. I was stupid enough to not check which direction I was going too so I can even use that and I don't know the XY and Z blocks to my house.

The only map I have is my Explorers Map and I'm still in the same spot on it as I started.

Is there anyway at all I can find my house despite all this?

Added (1). Yes but I think once a world is made in a certain mode certain features of that mode won't work. I've switched to creative mode before on my world but the flying ability doesn't work. The same with access to all items I can't open such a menu.

So switching to creative won't work because in a world originally created in Survival, switching to creative won't work.

Is there a way to change game modes? Go into creative and fly around

Happened to me i made a new base but i found my old one like months later by accident you could always build towers to help you find it easier
