I walked out

Long story short: I didn't have my initial radiation treatment today. We walked out of the office at 4:30. We had sat in the waiting area for 1/2 hour. I checked with the receptionist at 20 after and she said she would ask someone to come out and speak to me. I gave it another 10 minutes and then left, explaining to the receptionist that I couldn't wait any longer.
I walked out, but I haven't turned my back on that clinic or on radiation treatment. But I was feeling the pressure of time all day and having to wait with no explanation and seeing all the other patients waiting too (no one was called out of the waiting room the whole time we were there) and knowing how behind I was at home pushed me to the end of my patience.
Not that I was rude or anything. I just quietly explained why I was leaving, then left.
Sigh. I'm going to think this over and pray for guidance.
