We understand that you're going through a challenging time, and we're here to pray with you and offer biblical guidance. Firstly, we commend you for approaching your difficulties in prayer in Jesus name. The Spirit himself makes intercession for us with groanings which cannot be uttered. Likewise the Spirit also helps our infirmities: for we know not what we should pray for as we ought: but the Spirit itself makes intercession for us with groanings which cannot be uttered. And he that searches the hearts knows what is the mind of the Spirit, because he makes intercession for the saints according to the will of God (Romans 8:26-27 WEB).
Let's address the issues you're facing. It's important to honor your parents, as the Bible commands, "Honor your father and your mother, as Yahweh your God commanded you" (Deuteronomy 5:16 WEB). However, it's also crucial to set boundaries and communicate with them about the impact of their yelling. It's possible they are not aware of how it is affecting you, so discuss this with them calmly.
Here are some verses to encourage you:
Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus. Philippians 4:6-7.
Come to me, all you who labor and are heavily burdened, and I will give you rest. Take my yoke upon you, and learn from me, for I am gentle and lowly in heart; and you will find rest for your souls. For my yoke is easy, and my burden is light. Matthew 11:28-30
For the abusive situations you mentioned, we pray that God intervenes and provides a way of escape. Remember, God does not intend for us to live in a state of abuse or oppression. He says "Come out from among them, and be separate,' says the Lord. 'Touch no unclean thing. I will receive you. I will be to you a Father. You will be to me sons and daughters,' says the Lord Almighty." 2 Corinthians 6:17-18
Regarding your request for those who are oppressed by partners, we must address this biblically. It is important to flee such relationships, as they are not ordained by God. The Bible is clear about the behavior of believers. Moreover whom the Lord will destroy. For this, You mourn and lament; but the world will rejoice. You will be sorrowful, but your sorrow will be turned into joy. A woman when she gives birth, has sorrow, because her time has come. But when she has delivered the child, she doesn’t remember the anguish any more, for the joy that a human being is born into the world. Therefore you now have sorrow, but I will see you again, and your heart will rejoice, and no one will take your joy away from you. John 16:20-22.
We pray that God heals your parents and grants you a peaceful environment.
