Worried/anxious. . Am I wrong?

My guy had an outpatient hernia surgery yesterday morning and I have not heard from him yet. He told me I’d probably hear from him later after the surgery but I haven’t. I’m getting overly anxious at this point. My mind says he’s okay but the other part of me is like what’s going on. I’ve reached out of course but no response. Im just anxiously wondering. And apart of me is getting a little frustrated because I don’t know. Am I wrong for being frustrated? I have a million things going on in my head right now.
