The Apocalypse
Ok, this has a lot of potential, but it's going to take a lot of editing. I think if you put in the work, you could make it work!
First, make sure to always read what you read out loud. Serious. Record it and play it back. It will help you see where you need more detail, less dialogue and more action, where you are being repetitive and things like that. I really hope you do this. Honest. When you are doing that, also go back and fix the spelling errors you have.
You need to give your characters more time to react to whats going on. Thoughts takes seconds in real time and make the world of difference for the reader. I have no idea how your characters are feeling about this. I also have no idea how any of your characters look besides the main character, and then I only have a vague idea. If you have a picture in your head, make sure you paint it with words. You don't need to be super descriptive, but I don't know anything about the dad or the brother. I don't even know if the brother is younger or older. The damage done from the earth quake is something you could stand to describe more, and the neighborhood they are in too. the forest and the weather. All these things. Make sure you don't drop details like that. It's easy to do because you know what it all looks like, but we don't. And adding it in helps us connect with the story.
That being said, don't give us details about people (like their personality) that won't be relevant later. Like the bit you have about the mom. You could just simple have her interact, there is no need to tell us she favors Ben. It becomes obvious without it.
The town gathering could also use more detail, like how many people approximately? Is anyone being super helpful? Also, keep in mind actual limitations, like I have never seen a bag as big as what you have described. And if there a load of people, one person randomly screaming from a dirt hill won't be able to reach everyone.
If you want someone to die, please make sure you have in mind a specific cause, not just a death. Deaths are always supposed to be important. Make sure you don't have it lose importance by reducing the first death of a person to 2 sentences.
But I think just taking a second look and remembering that we need to know a lot about whats going on because we can't see what you can see will really help.
