Slipping

I'm starting to get worried that my friend is slipping away... not just slipping away from me, but slipping away from LIFE. And that scares me, it really makes me very afraid and very worried. What can I do? I feel like he's trying to reach out, but without anyone else noticing. I know it's up to me, I have to have faith. Dearest God, please help my friend. And please help me help him. I will not let this be his end. Amen.
