I have no one to contact besides him and after i called a few times his phone was turned off

He went to a company event a couple hours away. I'm not sure exactly where

Last i heard from him was around 2300 telling me the events almost over

It's almost 0400 and i havent heard from him

My mind is fucking taking over and i think he's hurt or something 

I'm panicking and I've taken my meds to help me chill out but they're not working at this point or at least not yet

Someone please help me calm down
