NEEDS TO BE FIXED NOW

I made a portal in my house, and then I showed my sister how to make one, deleted it, and then the portal to my house led to the portal I showed my sister, after I changed it. So now I am stuck and my best world turned into the trash. Can you make some way to let me get back to my house?!?!?
