[Grammar] Need help with homework

[martlo12]

Hi,I did my English homework,but I think there are some mistakes in ,which I can not find. Im grateful when someone can check this.

Nicknames​

Nickname is a short form of a persons first name, surrname or sometimes a humorous name, based on the persons character or habit. Nickname is a name given to person in addition to his personal name. What nickname you get depends of many things. It depend your name, your family, your clothes or even your acting.
I dont have nickname now, but used to people called me mädik. I liked that nickname. Now Im called Märt or just Lõhmus. I dont use many nicknames when I talk with someone.
My brother name is Karl ,but I like to call him Karla. My classmate Kristel is called Krissu, Maarja sometime Mammu and Agnes nickname is Aku.
Nicknames can be bad too. Someone who hate you can put you a nickname, which you dont like. I think its not funny when someone do that.

The main problems were the articles - 'nickname' needs them - and your complete absence of the apostrophe.
