Help Editing Letter………………….?

I need to make a letter for my lard lord regarding my current parking space so this is what I have…it sucks i know…lolz please help me edit it..thanks

Dear Ms. Landlord,

I formally requested to keep my current parking space due to my son’s unique needs. From time to time I have some social services and therapy come to check on him. So it’s essential for me to have available parking space for those special occasions.

My son, he has ADHD. Which is stand for Attention deficit hyperactivity disorder (ADHD) is a condition in which a person has trouble paying attention and focusing on tasks. For his safety, my current parking spot lessens the dangers around him. Because it is much closer to my apartment. As a Single mother, I really need your cooperation.

Thank you in advance.
