Don't give up. You have good ideas, you just need to work on presenting the material, that's all. It just takes a little practice, hun, it's okay. You're only 13, you have Loads of time for your writing to evolve. I promise :D
Read chapter. You've got a good plot going. Most of the story flows, but writing "fast forward 30 minutes" kinda interrupts that nice flow. You say she woke up late? Tweak it slightly to where she realizes "OMG, I'm late!" and runs out the door and fights the traffic. Writing "ff 30 mins" seems like you can't figure out anything to put there, but with your creative mind, I doubt that's plausible.
Now, I'm not being mean about this, I'm just wanted to give you some advice I had to learn for myself. Sorry if it seems rude.
Nice life plan =D I have a Acer desk top but I'm hoping to get a laptop for Christmas! Now I just have to find a laptop that I like and have everything I need in it.
