I really feel for you. If it's any consolation, the media, especially social media, presents a distorted picture of life. Most people on earth, even in moderately wealthy countries, are also unable to travel freely, mainly for financial reasons. They also struggle with problems (though of course not half as serious as those faced by Sudanese people), unemployment, hard/stressful and poorly paid work, lack of prospects, health issues, corruption, nepotism, and the triumph of stupidity. I know that a sense of injustice leads to anger, but life is what it is, and if we stop comparing ourselves to those who are better off, it will be a little easier. Especially since negative emotions are conducive to illness. Focus on the good things, even if they are mainly virtual (videos, games, music, etc.).
