Could anyone correct my essay, please?

I have many best friends. But Dat, one of my best friends, made a deepest impression on me. I haven’t met him since I moved to my new school. It lasts about three years.
Dat is medium high. He has short black hair. His face is nice with black eyes and his mouth always smiles.
He is a humorous person. He used to tell me funny stories or sing funny songs which he made his own lyric. He is not the best student in our class, but for me, he’s very smart. He knows how to behave his friends. Sometimes, someone really makes he annoyed, but he calms down and find the way to solve the problem.
He is also a skillful goal keeper! He often helps our football team from losing other one. Now, I miss our football matches. I miss him. Maybe I will come back my old school to visit him after my next two exams.
How about your best friend? Let’s tell me.
