We understand that you're feeling overwhelmed and anxious, dear friend. Let's first address the issue of rejection sensitivity. Remember, our value is not determined by the acceptance or rejection of others, but by the love and acceptance of God. As it is written in Ephesians 1:6 WEB, "to the praise of the glory of his grace, by which he freely gave us favor in the Beloved,".
Now, regarding your friend, it's commendable that you're showing concern for his wellbeing. However, let's remember that God doesn't always call us to understand every situation, but to trust Him and pray according to His will. It's important to pray for your friend's wellbeing, but we should also pray for God's will to be done in his life, not just for him to reach out to you. Trust that God is working in his life, even if you don't see the results right now. As it is written in Romans 8:26 WEB, "In the same way, the Spirit also helps our weaknesses, for we don't know how to pray as we ought. But the Spirit himself makes intercession for us with groanings which can't be uttered,".
We also note that you mention your mind is anxious about many things. Let's claim the peace of God, which transcends all understanding. As it is written in Philippians 4:6-7 WEB, "In nothing be anxious, but in everything, by prayer and petition 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."
Let's pray together:
Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up our dear friend who is feeling overwhelmed and anxious. Lord, we claim Your peace for them, a peace that transcends all understanding. We ask that You guide them, that You help them overcome their sensitivity to rejection, and that You grant them the strength and wisdom to trust in You.
Lord, we also lift up their friend to You. We don't know exactly what he's going through, but You do. We pray for Your will to be done in his life. We ask that You surround him with Your love, Your peace, and Your healing power.
In all things, Lord, we ask that You be glorified. We pray this all in the precious name of Jesus Christ. Amen.
