IF ANYBODY HAS THIS PROBLEM: (For future reference)

Enter creative mode, build a nether portal inside the alternate dimension. Go to the nether, then walk back through the portal and it will take you back to your normal world. Kill yourself to respawn or teleport to another player if you want to keep loot.

Source: just had this problem and it was literally making my eyes bleed with frustration.
