In general, people who are afflicted with many trials and tribulations are the most closest to Allah swt. If you experience many problems in this world, it could be a blessing from Allah swt, to purify you from your sins; (so you're saved from punishment in the next life), to allow you to appreciate the good times, to increase your emaan and so on.
