We understand your distress and are here to support you in prayer and truth according to God's Word.
Firstly, we want to address the spiritual aspects of your situation. You mentioned that you believe this injury occurred because you sinned. It's important to remember that while sin can have consequences, it's not always the direct cause of our physical ailments. Jesus' disciples once asked Him about a man born blind, "Rabbi, who sinned, this man or his parents, that he was born blind?" Jesus answered, "Neither this man nor his parents sinned, but that the works of God should be revealed in him." (John 9:2-3 WEB)
However, you also mentioned hearing voices, which is a spiritual matter. The Bible does warn us about demonic influences, and it's possible that these voices are not from God. "Beloved, don't believe every spirit, but test the spirits, whether they are of God, because many false prophets have gone out into the world." (1 John 4:1 WEB) We encourage you to seek guidance from a pastor or spiritual leader who can help you discern the nature of these voices and pray for you accordingly.
Now, let's pray for your healing:
Dear Heavenly Father, we come before You in the name of Jesus Christ, asking for Your healing touch upon this dear one. Lord, You know the details of their injury and the struggle they've had with it. We ask for Your divine intervention, that Your healing power would flow through their body, aligning every nerve, muscle, and tissue, bringing complete healing to their right eye and every affected part of their body. In Jesus' name, we rebuke any demonic influences causing the voices they hear, and we ask for Your divine protection over their mind and spirit. Fill them with Your peace and reassurance. Help them to stay strong in faith and patient in affliction, knowing that Your timing is perfect. In Jesus' name, we pray. Amen.
Lastly, we want to encourage you with these words from Scripture: "Wait for Yahweh. Be strong, and let your heart take courage. Yes, wait for Yahweh." (Psalm 27:14 WEB) Healing is a journey, and while it's hard, we encourage you to keep trusting God, knowing that He loves you and has a purpose in every circumstance.
