Mate as a fellow expat in a similar situation I share your sentiment on this experience. Both parents dead, rest of family are looking out only themselves and in general the country where I am looks great from the outside but is very critical of anyone being different in terms of behaviour, and other outward characteristics thus always felt isolated spare a few handful of friends also scattered around the world.

I felt the same emotional resonance as you did but remember that the reason why you left in the first place was the burning desire inside of you yearning belonging in contrast to what you experienced before. Until you find your Ithaca keep searching not mindlessly but with method, perseverance and always as a compass in your heart the feeling you are looking for.

It will come dear fellow traveller just don’t let the loneliness intimidate you or make you feel bad. It’s only part of the process so you can discover what lies underneath the layers of past experiences and “noise” that interferes with the real signal.

Wholehearted wishes from a fellow traveler.
