Show the truth

Dear Allah. What is happening at me actually. Help me please. Someone. Allah. There's something bothering my mind. But i don't want is it. I keep asking myself what happen to me. But i still haven't get the answer. When i'm in the crowd, i feel sad, sometime lonely and i feel senyuman aku, kebahagian aku ditarik oleh sesuatu. Mana aku yang dulu? I needs to know the reason now and i don't know where i can find that reason. I won't keep praying and hoping. Dear Allah, please tell me what should i do, show me the mercy and give me strength. Please.
