A protagonist that embodies the flaws and weaknesses of the writer distracts the reader from the narrative itself? Agree/disagree?

So are we easily distracted when a writer embodies parts of their own problems into a character? I would say I have somewhat mixed feelings over this matter. I can see how on the one hand, pouring out your weaknesses into a protagonist can seem like a desperate plea for attention rather than effective storytelling. However, I also see that often the best writing comes from the flaws of the writer themselves as they can connect more this way. I personally always insert part of my own traits into a character, whether it is intentional or not. Emily Dickinson was troubled from a young age by the ever looming effects of numerous deaths in her family. This became her weakness and much of her poetry focused on the subjects of death and immortality. The pain from these experiences came out more in her later works. The poem " My Life Closed Twice Before Its Close" is a clear example of her feelings over these deaths. The poem seems to say that she has lost two loved ones, and the pain from these losses felt worse than death itself. This is an example of where we become distracted by the writer's own weakness and cannot look beyond this to see the possibility of fiction. I feel every writer does at some point, but it can strengthen characters and make them more relatable. Sometimes we need to embody part of ourselves in our characters to feel a closer connection with them and give ourselves relief from these inner flaws.
