Really worried about my boyfriend

I haven't heard from him since yesterday, he hasn't been online since then, I'm really worried about him, I pray he's okay, I have anxiety and when this happens my anxiety makes me have bad thoughts and I wish I didn't think like this, but it happens, all I want to do is talk to him, I always feel better when I talk to him, because i know he's okay, but right now I have no idea if he is ok or not that's what's killing me inside,
