World Wont Load When Leaving Nether

When Going Into The Nether Everything Worked And Loaded In Fine, When I Went Into The Portal To Leave I Was Left On The Loading Screen For more than 5mins before my game crashed, when i rejoined the game i was still in the Nether so tried again and same problem, so now currently stuck inside the nether and cant leave, (not tried killing myself but i think will also make my game crash) (sorry if its a double report)
