First notebook entry: Introducing myself

Hi,

My name is Golnaz. My nickname pseudonym  is Nazita. Both of them are flower names of flowers. I live in Iran. Therefore my native language is Farsi.
I'm a university student. I'm studying medical engineering. I'm learning English because I would like to work abroad. I can improve my vocabulary and listening skills through self study by myself but  while I usually make some mistakes in my writings especially from grammatical aspect which need to be corrected by someone else as i cannot persive them by myself. I need some help to improve my English.

Nickname is usually a funny name given to you by your peers but Nazita is just a common name in Iran, so i thought pseudonym would be a better replacement although i'm not sure of its correct use.
