(Minecraft) Died in void, my bed was destroyed, I cant find my way back, Help

(I’m in creative) I was making a new house with the new mod pack I just got, I finished the structure and flooring and I was working on decorations, my bed was destroyed, that’ll be important later. I needed a long water source under my sink, so I started digging, but then I hit bedrock… I broke it and went into a void… My bed was broken as said before, And I can’t find my way back.
