Living abroad stretches you and stresses you at the same time, and it helps to know the emotional arc is normal. Most people cycle through excitement, a dip a few months in when novelty fades, and gradual recovery as competence and connections build. Loneliness, decision fatigue from unfamiliar systems, and guilt about distant family are the most common ongoing loads, and they surface even when life looks objectively good.
What reliably helps: structure and routine early, since exercise, sleep, and regular rhythms anchor you; real social contact rather than only screen contact, which usually means joining something recurring; learning the language, because helplessness in daily tasks corrodes mood; and scheduled calls with people back home rather than leaving contact to chance.
Do not tough out a persistent slide. Online therapy makes support available in your own language almost anywhere now, many employers include counselling in benefits, and treating a rough patch early prevents it hardening into something that ends the whole adventure.
