No offense intended; however, considering the quality of your English, you're lucky to have been employed as an English instructor in the first place. That being the case, it is difficult to sympathize with your plight, as in the first place you were obviously hired without the necessary qualifications.

As I am just passing through, it will not be necessary to respond to this post if you will be expecting me to see a reply. However, I do want to add that by reading numerous other posts in these forums one can only be dumbfounded by the level of English to be found here. I would think that to be an ESL or EFL teacher one should have, at the very least, a college level command of the language. Unfortunately, that is apparently not the primary concern of employers who obviously hire for reasons that are perplexing at best.
