help me! please

I want to know if this well written...


when I was about two years old,
a cousin of my mother used to play with me every day,
then he died in a traffic accident five days later.
(Specify the time here- A day later, A week later,) my mom was playing with me and she left me single alone in the room. 
Ten minutes after later,
when she came back she heard me speak,
as if I was talking to someone else. 
She was scared and approached me and asked with whom I was talking,
then I told her that I was speaking with Mario, who is the cousin of my mother,
she was scared, and (brought?) me out of the room. 
when While we were leaving I said bye Mario,
after a while my mother was calm,
and (she or I? Specify the subject) thought that Mario was saying goodbye to me.

My English teacher

I am taking an English course , I'm so happy to learn a new language but l can't communicate with my teacher , He is American and he speaks so fast.
Whenever he asks me something, I asked him to repeat what he said again and again. (Again doesn´t have a space)
don't you think that we should learn with someone that we can communicate with each other??

I think if you try hard enough, you can succeed! The harder the challenge, the more satisfying the victory :) You're doing so well already!

Notes

Praticando: Anotação N. 01
Well, learning english without specialized courses is not so very easy. Until then i've learned only the basics on from school and the most of that i know, was from reading books of in english at home. But it's so awesome, so i think arriving at the end of this job will be awesome!

Good job! Keep up the good work!
