Okay, I just read about half of your story.
My critique - and I am trying to be gentle about it:
1. It is too choppy. Your sentences do not flow. You start and stop at strange places. A sentence should be one complete thought. Try varying the lengths of your sentences for a more interesting read.
2. Some parts do not make sense. Why would we think your mother died during a shopping trip? There is nothing in there that indicates she may have died.
Also, if they left at 6:26 and returned at 6:52, that means they've only been gone for 26 minutes. Given that it takes time to get there and come back in addition to actually shop, how did they do that so fast?
3. Paragraphs and white space. Make use of white space to give your readers a chance to rest their eyes. Paragraphs are there to contain trains of thought. Each paragraph should have one idea or a complete thought. When you change perspectives or start talking about another subject, you must start another paragraph. AND use white space between paragraphs.
Each speaker in a dialogue should have their own paragraph, even if it is only one word. This is to avoid confusion.
In your question, you state that you are only 13 years old but in the Additional Details, you write "by the way everything until i turned 13 or 14 or something like that was real". That is confusing.
I must say that your spelling is quite good although you have a few typos here and there, but that can be easily fixed.
If you're interested in writing, I encourage you to keep practicing. The more you write, the better you will get.
Good luck and have fun.
PS - I agree with Corelila about it being an information dump. What that means is that it is not really a story. Instead, all you're doing is listing a line of events.
A story needs a great plot, character development, a conflict and a resolution.
