I'm currently experiencing this.

I have a friend who i talk to on a regular basis. We both live alone so we kind of support each other especially with all the Coronavirus restrictions about at the moment. We talk a lot through WhatsApp and I noticed that he hasn't been online all morning (he usually checks it first thing to get his shift pattern for the day ahead) and he also hasn't been online on another app we follow each other on.

I decided to text him to ease my worries but I'm not getting reply. He's the type to always have his phone on him so I'm getting very worried now. I kind of know his routine for the day and I can't think of anything going on right now that would keep him away from his phone? I'm going mad with worry to the point that I'm sat here shaking. It's very out of character. 

Any tips on what I can do to calm down?
