Great story, I enjoyed reading it. Moving abroad is never easy, and moving back is always harder than the move itself, whether planned or not. I've moved abroad and come back 3 times now (once planned, once after "giving up" on a place, once after simply having enough), and very few people will understand that re-entry is the worst! A large Israeli community should help, though.
Best of luck with whatever you decide to do next!
Edit: Someone sent me this, and I think it captures it fairly well.
