“Just like that, you keep me, as if I were some stray puppy.” She turned to hide the tears threatening to flow.
Yes, this shows more stress!
In fact, I think you can take it even further. She’s just learned a life-altering secret. Consider losing the commas and taking her all the way to incomplete sentences and some repetition. Something like:
“Just like that. You keep me, just like that. As if I were a puppy. A stray.”
Incomplete sentences allow the reader to hear the character struggling to speak–and that’s what you want to depict here. Never be afraid to ditch grammar in favor of high emotion!
