I strongly believe the power of Du'a or prayer. In times of worry or sadness especially Du'a will always be my best friend...I would be reciting it most comfortably in BM rather than arabic because I know Allah knows better and more...(than anyone else in the world). Reading some verses from the Quran is also part of Du'a. In fact, I always get this instant calmness and relief every time I read the Quran.
In al-Qur'an, Allah Subhanahu wa Ta'ala says:
"When My servants ask about Me, I am indeed close to them. I listen to the prayer of every supplicant, when he calls on Me. Let them also, with a will, listen to My call, and believe in Me, so that they may walk in the right way"
Reciting a Du'a shouldn't be the last resort however....(I used to do that before Allah granted me with a little wisdom). Even when we're at our happiest moment, Du'a should always be recited so to maintain the joy at the longest period. So, jom du'a everyone! Believe me, u will not regret.
