Suggested corrections:

I am an English teacher. I have worked as a teacher for one year. Actually I love teaching because in this way I can help people. All of my students like me and they always keep telling me that I am the most patient teacher that they have ever seen! Honestly, I am not knowledgeable enough yet to teach higher level courses than what I am currently teaching. What is important to me is that I am enthusiastic about my work. It makes no difference which level we teach. What is really important is how responsible we are with our job.

Here are corrections for some minor misspellings and some suggestions to say this a little bit better:

I am going to write about my best friend whose name is Esra. I have known her for 7 years. She is actually the kindest person that I have ever met in my entire life. Whenever I run into problems she helps me and Esra is also the only person that I must talk to at least three times a day. Otherwise I feel as if I have lost a valuable thing!

This was well written. Here is your entry rewritten with spelling corrections and a couple suggestions for rewording.

Nobody argues that English is a need and everyone should learn it so I have been studing for 2 years. Honestly, at first I hated it but after awhile I found studing English to be really inspiring! Now I love it and I hope I can become as fluent as possible.
