The difference between the cry of the righteous and the cry of the unrighteous is that one is noise to God’s ears, while the other is like a sweet-smelling savor that attracts God’s attention. If you have asked God for something and it seems He is not doing anything, it’s time for you to do a deep introspection. Put your life in an x-ray and examine it to know if you are involved in sinful activities or living righteously.
God’s Word in Isaiah 59:1-2 says, “Behold, the Lord’s hand is not shortened, that it cannot save; neither his ear heavy, that it cannot hear: but your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear.”
God is interested in saving you from your troubles, but His eyes are too pure to behold iniquity. Also, He cannot dwell where sin is because He is too holy (Habakkuk 1:13). Therefore, you must first allow the precious blood of Jesus to cleanse you and make you holy. Then, God will draw near you, commune with you, and help you fix your problems.
Are you struggling with unanswered prayers, and it seems God does not care about you? Why not consider your ways and choose to live a holy life?

Dear Heavenly Father, I ask that You forgive all my sins and iniquities. Wash me with the precious blood of Jesus, take away every sin that has become a hindrance to my prayers, and make me holy and presentable before You. When I call you, please answer and save me from my troubles. Let my prayers and supplications rise to You like a sweet-smelling savor. Open my ears to hear Your voice and get instructions that will transform my life positively. 
In Jesus' name I pray. Amen.
