I am writing a third person story that focuses on a main character. Sometimes I want to express the internal thoughts of the character, but I don't want to use internal dialogue in italics. What's the best way of doing that?
This is what I have so far:
Mandy arrived at 3:00pm, but he was nowhere to be seen. Her mind immediately flooded with panicked thoughts. Was making the request via email inappropriate? Had he gone back to California already? Was he simply caught up in the traffic? She realised she was simply being neurotic and so took in a few deep breaths. The yoga techniques she had learnt might have seemed silly, but they certainly were better than worrying. She paced around, taking in the sights of the street. However, after an hour of waiting it was clear that he wasn't coming.
The three questions are obviously something the POV character is thinking, as are the comments about the yoga techniques. I thought this would be clear, but I get complaints from my readers that the text shifts POV. What's the best way of approaching it?
I know I can just use internal dialogue in italics, but I personally always find that it spoils the flow of reading.
