I'm here would like to express my feeling when I found this website. Please help to correct my grammatical errors

My english is very poor. I have been applied English into my work for 5 years but my grammer and essay writting is classified as very poor. Sometimes, it cause my customers and vendors could not understand what I was trying to express. This is the sadness part of my life now.

Right now, before I sending my email, I will send to my friend for checking. I never seen there is no rectification on my orginal sentence. When he is busy, he will kind of criticise me. I feel down whenever feel like always need to rely on somebody and always being criticised on poor english.

Except poor gramattical problems, my vocabullary is limitted. Can anyone tell me how to increase my vocabullary's ability?

Hence, I decided to search online for online learning English and I found English Forums and reading some of the articales posted. I feel very happy because the people here are kind and helpful!

Nice to have you here too, Kino!
hi Mister Micawber

Could you please rectify my doubt in the above being corrected paragaraphs by you becaue English is my 3rd language .So i am not sure.

There was a sentense " I will send it to my friend for checking "
As far as my knowledge is concerned it had better be like this "I used to send it to my friend for checking "

Please correct me if i am wrong and if you are also not sure than i will ask from some native speaker .

Thanks.
Site Hint: Check out our list of pronunciation videos.
Kino says 'right now', so it cannot be 'used to', which is past habit, Fasi. However, Kino himself will have to tell us what he actually means to say.

PS: I am about as 'native speaker' as it gets, Kino.
Dear Mister Micawber

You are right. Kino himself has to clear what exacly he wants to say.

According to my perception. I am taking it like this.

Original Sentence
" Right now, before I send an email, I will send it to my friend for checking. I never see any corrections of my original sentences "

Right now means .............. Right now ( means present )
before I send an email .......... He means before sending any email to anyone .
I will send it to my friend for checking ........ He means he sends his emails to his friend to make them correct ( past means whenever he sends any email to anyone so before sending them he used to send them to his friends first to remove the grammetival errors then he sends them farward ) ( He is saying all this in present but involving some past it in)

" I never seen any corrections " ............ His means that he never found any correction(He is telling us in present but talking about past .

This is what i think dear .
Anyways you are always welcome to make correct even if i wrote some thing wrong IT WOULD BE MY PLEASURE .Because I am a learner .

Thanks .
