My job

Hello there!
I'll I'm going to tell you about my work.
I work in an elementary school with the handicapped disabled children.
I help them to eat, move, go to the toilet, exersise, etc..
One of them frequently runs away from the school and
to gets on the subway.
One day, he the one who likes to run away were was caught in 300 km away from the school by the police!
I was extremly worried him.
When I think about it, always I'm nervous, It makes me nervous just thinking about it, even right now.
Another child is very violent.
The child He hit my face and my glasses were thrown.
Sometimes, he bited me until it I was bleeding, or teared my clothes.
Ironically, I love him the most.
I don't know why I do. XD
But sadly, I can't meet see him no any more.
He changed to another school.
Besides, there are many children.
I was saying lots of negative things continually but you should know they are actually lovely, adorable, pure than no one and more innocent than anyone.
They dance,sing for me, tell me "I love you teacher"
Sometimes they make me being counfused confuse me but I can't dislike them.
I've been working worked at here since 2013 year and I'll finish working next month.
It's too/so sad to separate part from them.
I'll never forget this experience at the school for 2 years.
So, thanks for reading and I have to go work!
I think here are many grammartical mistakes mistaking.
Could you correct this, please? Thank you!
Goodbye!!

This is really good, I enjoyed reading about your job. :)
