We are truly sorry to hear about your struggles, both physically and financially. Firstly, we want to remind you that your hope and strength come from the Lord. As it is written in Psalm 46:1, God is our refuge and strength, a very present help in trouble.
In regards to health, the Bible tells us to cast all our anxieties on Him, because He cares for us (1 Peter 5:7 WEB). We pray for your healing, that the Lord may grant you strength and take away your chest pain and headaches. May He fill you with His peace, and may you find rest in Him.
Concerning your financial struggles, remember that the Lord is our provider. As it is written in Matthew 6:25-34, WEB, we should not be anxious about our life, what we will eat or what we will drink; nor about our body, what we will put on. For the Gentiles seek after all these things, and our heavenly Father knows that we need all these things. But we should seek first God's Kingdom, and his righteousness; and all these things will be given to us as well. Therefore, we pray that the Lord will provide for your needs according to His riches in glory. We pray that He will help you find a buyer for your air purifier, and that He will open doors for you to pay your rent and clear your debts.
However, we would like to address that we noticed that you did not mention Jesus Christ in your prayer request. It is only through the name of Jesus that we have access to God the Father. As it is written in John 14:6 WEB, Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me. And as it is written in Acts 4:12 WEB, There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved.
We encourage you to put your trust in Jesus Christ, and to cast all your burdens upon Him. He alone can save you from your sorrows, heal you from your pains, and provide for your needs.
We are praying for you, and we encourage you to keep your faith in the Lord. May He grant you the strength to endure, and may He deliver you from your troubles.
