I have been in your shoes. It is not easy being corrected, sub or not. I am not sure of your story so I will speak from my personal experiences. We have been doing TTWD for almost 9 months now and I still get corrected almost everyday for my “tone”. Even when I am frustrated at other things in life I tend to take it out on my Sir. I am working on that, but there are days that I feel like I try so hard and still fall short of his expectations. However most of the time once the anger and frustration passes I see that he is right. It is my vanilla reaction to snap back and tell him he expects too much. But is it really too much to communicate respectfully to him my anger or frustrations? No, its not. When I start to feel the feelings you describe I do what master pet suggests, I ask him for downtime. The posture for downtime, kneeling with your head in your Dom’s lap, helps keep me mindful of my tone as I tell him how I am struggling to please him. This gives him the opportunity to change my train on thought with his kind words. He will recognize my efforts and reassure me that I do make him happy. Communication is one of the foundations to D/s. If you are not having regular downtime I would suggest bringing it up to your Dom and see if you can make it a weekly ritual to help evolve your communication. LK has several blog post on the topic of downtime I recommend you read to get a clear view of what I am talking about. Come on over to chat if you need to talk about it more.
HUGS!
