Of course you know your spelling is bad. And at times your sentence structure is bad as well. You tend to put words in the wrong order at times (syntax). You need to find ways of mixing up your sentences so they don't always start the same. People who write in first person tend to start way too many sentences with "I". Also your dialogue is very flat and lifeless. That is because you don't know your characters well enough. You need to do more character studies so that you start to flesh out your characters and make them real people. Then, they won't all sound so flat and wooden.
The biggest cliche in writing - and one I see here thousands of times - is opening with a weather report. Unless there is a very good reason for it - avoid it. It is "telling - not showing". Same thing goes for giving a description of yourself. You need to put those types of things into the story actively.
For instance the mother could yell up the stairs "It's raining today, Arabella, make sure you bring your raincoat!" Then I am showing - not telling.
Lastly Arabella. That is a name I would avoid at all costs. Right now every kid in America is writing a book about a kid named Bella. A good author knows that means they should step out of the box - and get as far away from that name as they can.
Hope that helps. Pax-C
