How to get back from the end biome?

I defeated the dragon and went trough portal and after a long looooooon search i finaly found the ship and there it was elytra! I placed it in the endchest and now the only thing that i want is to get myself out of that damn void world. Its much more fun when you can fly and dont have to wory about falling into void. But i didnt see any portals trough whole jorney so i dont know how to get back now.. I can put all my stuf in one shelkur box and place it in the end chest and just kill myself, but i dont want to lose 84 lvls if i dont need to..
