nether portal

i entered the nether when my overworld coordinates were 6680 10 -2328 and i went straight to the nether coordinates 6680 10 -2328 same as the overworld when it should have been 835 10 -291 and there was no nether portal in sight i was literraly trapped in the nether cuz i bugged to the wrong coordinates and the nether portal i used to get there wasnt there OR the proper coordinates it should have gone to in 1.14.50 (education edition)
