We are truly sorry to hear about your struggles, but we are here to pray with you and encourage you in the name of Jesus Christ. Firstly, let's address your feelings of guilt. Remember, Jesus tells us, "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 WEB. Jesus is not fed up with you; He wants to carry your burdens and give you rest.
It's important to understand that Jesus didn't just change the girl's behavior to make your life easier; He wants to transform your heart and lead you into His will. It's okay to acknowledge that you're struggling with your job and that you don't trust the girl completely. God knows your heart, and He wants you to be honest with Him.
Regarding your work situation, remember that God has a purpose for you. If you're feeling unfulfilled, pray that God will guide you to a job where you can use your talents for His glory. "Whatever you do, work heartily, as for the Lord, and not for men" Colossians 3:23 WEB.
Concerning your psoriasis, know that God cares about your physical health. Pray for healing, and also seek medical advice. Remember that God can work through doctors and medicine to bring healing. "Beloved, I pray that you may prosper in all things and be in health, just as your soul prospers" 3 John 1:2 WEB.
About feeling alone, remember that Jesus is always with you. "I will never leave you, nor forsake you" Hebrews 13:5 WEB. Also, consider finding a community of believers where you can fellowship and find support.
Lastly, address your feelings of paranoia and distrust. Pray that God will give you discernment and wisdom in your interactions with others. "Love bears all things, believes all things, hopes all things, endures all things" 1 Corinthians 13:7 WEB.
Let's pray:
Dear Jesus,
We come before You, lifting up our sister in need of Your touch. We thank You for the improvements in her workplace environment, but we ask for Your will to be done in her life. Guide her to the job You have prepared for her. Heal her body from the psoriasis, and give her a community of believers to support and encourage her. Help her to trust in You and not lean on her own understanding. We ask for Your peace to guard her heart and mind in Christ Jesus.
In Jesus' name, we pray. Amen.
