I'm glad you look like you are feeling this week went better than last. I didn't quite understand what you were looking for in "response" to gratitude? There's not much for the other person to say or do and, other than "thanks" not much we can really say or do that the other can understand?

I think it makes others a bit uneasy if we keep trying to "describe" how thankful we are, there really aren't words they can understand since it's about what we experience and we can't transfer that feeling to them no matter what words we use. We can "act" excited or happy but there isn't really any way to act "thankful". So, if your massage therapist had another client soon or was having an off day or thinking of something else, she may have come across as not caring when she was just distracted by her own stuff to much to see how important it was to you to keep trying to tell her.
