I'm really sorry to hear about Joey's struggles. Here's a prayer for you and him:
"Dear Lord, please watch over Joey as he serves in the navy. Comfort him as he deals with his health issues, both physical and mental. Please guide the medical professionals as they treat his IBS and cough, and bring healing according to Your will.
Lord, Joey is also struggling with depression. Please surround him with Your love, bring comfort to his heart, and guide him back to finding joy in You. Help him to feel Your presence, and to remember that You are always with him, no matter where he goes or what he faces.
Please also be with his family, especially his mother who is worried about him. Grant her peace and trust in You.
In the name of Jesus, we pray. Amen."
Please encourage Joey to seek professional help for his health issues and depression. There are also many support resources available for service members like military chaplains, counselors, and support groups.
