Don't Know What To Do

Now I've become friends again,
With someone I once knew,
I've noticed certain changes in them,
They just seem so blue.

I'm really starting to worry,
About this person called my friend,
Things that they are doing,
Might make their life come to an end.

I know I'm not qualified,
To help this person out,
But making people feel better,
Is what I'm all about.

Doing things that may hurt,
Won't make people see,
That what he is doing to himself,
Is truly scaring me.
