It seems to me that you are simply too focused on the main events, and you have nothing to be distracted by. There are many layers of the work in which you can reveal the essence of what is happening. Internal moments of philosophizing on various topics. What actually happens may not always be fully understood by the character or narrator without further thought or action. Also, the story itself may be incomplete. You may now think that everything is about to end, but I think that you have not fully thought through the world around you and the possible events that may still happen.
You can also imagine that you don't like what you write. To do this, you can look for opinions or votes on similar topics that occur in your story. And try to explain to this conditionally negative critic that he is mistaken, through his narrative. For example, some words are tied to society, like the concept of an outcast. Somewhere in an Indian tribe it is normal to sit in a yurt with a spear and eat a caught rabbit, but in the modern world this would be an outcast. In this view, one can present a lot of different material that explains in advance the incorrect view of the critic who does not like outcasts. And instead of pity, evoke empathy or, on the contrary, make you hate the character even more.
Even the fact that you don’t like that the story is moving too quickly, you can reflect in your work through the characters, and talk about this topic through them. This is, in principle, one of the things that should accompany the author when writing - you must experience the events that occur.
