Guilt and shame

I wrote a book about a refugee woman and I have some interviews scheduled with journalists to speak about this project.
I have some thoughts that are not helping me in this task.

C My character in my book
T She is a victim of a system I’m part of
E guilt
A give money to association, ruminate, say whatever during interview, stammer
R I make my own work useless in this situation

C My book
T I appropriate the story of vulnerable people I’m not part of
F shame
A say whatever during interview, ruminate, don’t see the value of my work, don’t see the value of me talking about the project
R don’t show up as the author I want to be

I wrote another model which is helpful:

C Interview
T It’s a wonderful book and I want to defend it 100%
E Enthusiasm
A I listen to the questions, I answer from the bottom of my heart, I remember what I prepared, I write down the questions for the next interview, I talk about my collaborators, my experience, my work, the connection felt throughout this experience
R I am the professional I want to be and I am promoting the book well

But I’m afraid to miss something, which would be, it’s ok to feel guilt because I think refugees are not treated the way they should be? I may want to think there is a problem?
And I think that my book is good, but that people are waiting for me to be an activist, to have a real commitment in politics, and this is not the case. I have no solution to offer so that the situation of refugees could be improved. I was interested to write the better story I could.
And what about shame? Should I keep this feeling? I think there is no upside to it?
Could you help me to gain more clarity? Thank you!
