I spent may a days and nights in the shape you are in...the thing is you can't look over them 24hrs. Each time they pick up it is like a game of Russian Roulette. Then they pull crap like tell you they are going to kill themselves purposely.
I spent nights and days driving around searching for him, sometimes I found him sometimes I didn't...and some of the times when I did find him I wish that I hadn't, he was lucky to be alive after I left.
You body can only take so much of the worry, before you get sick yourself.
