We are suffering because of our sins. It is because of our disobedience that we are suffering. We suffer because of our evil ways. The reward of sin is suffering. The wages of sin is death. Death produces suffering.
The evil one has planted the seed of suffering in our lives. He did this by teaching us to disobey God's commandments. When we disobey God's commandments, we become the enemies of God. The blessings are for the obedient. The disobedient will have suffering and pain.
God created us in His image. He created us to be like Him. We were blessed with all the things that should make our lives better. The God who created us does not know suffering. He has no reason to worry or suffer. So, when He created us in His likeness, we were to enjoy abundance and live in abundance. Suffering was not God's plan for us.
To be free from the suffering in this world, we would need to reconnect back to God. To get back to God, we need Jesus Christ in our lives. Surrender your life to Jesus and keep the commandments of God then you shall be free from every suffering.
