It seems that you are an unhappy person and you carry your misery everywhere you go. When you were at home you were not happy (and you conveniently blamed it on your brother's tantrums), now you are away and you are still not happy (and are blaming it on language barriers). You are the kind of person who could be put in God's Paradise and still find a reason to be unhappy. Trust me, the reason for your unhappiness has nothing to do with the language or the people. Many people go on vacation where they do not know anyone and cannot speak the local language but they enjoy themselves and have lots of fun. And I really don't see how your brother's tantrums are such a big problem for you that it could make you want to escape the country. You're not exactly your brother's caretaker, so let those saddled with the responsibility of taking care of him be the ones to complain about his tantrums. What you need to do is look deep inside and discover the real reasons for your unhappiness. Maybe what you need is love, a cute boyfriend/girlfriend who chats with you all the time, a sweet and joyous romantic relationship with someone who adores you, and then all the problems around you will cease to have any effect on you. Whatever the real cause of your unhappiness is, you need to discover it and address it, because going back home will not take your sadness and loneliness away.
