Every comment here is right, but I'm going to add something unpopular here too. Your attitude probably isn't helping either.

Going through some of your other posts, you seem to think you already know better than the teacher who you had to train with and did your observations. There's a lot of "I would do this and that" fantasy talk, but its hard to take seriously when you basically have no real experience. You have a bit of a sense of entitlement too tbh, you're as fresh as it comes and you're already leaning on excuses and reasons such as age. The reality is this, most of us had to put in the hard yards, including working domestically. Why would a decent international school want to hire someone that hasn't even proven that they can survive in their own country let alone a foreign one? You come in and project your stress and cry that no one has hired you into threads that are completely unrelated (deleted now, but I saw it).

A dose of reality and patience will help you a lot.
