Learning a language just takes practice! It's not easy, at first, but you just have to keep trying and learning more. Also, you use "Confusion" a bit incorrectly. Confusion is a noun (person, place, thing, or idea). You should use "confused". It's a feeling. So, this sentence "i have something really make me so Confusion". Would make more sense if you typed: "I have something that really makes me confused" The rest of my changes are just minor things to make it sound more correct, but you understand it the overall of it.

I'm sorry to hear about your problem. I would like to try to help. First, you wrote a very understandable question, so you should be proud of your English. I am confused. You are in China and you work for the Italy office of what organization? And you are expected to speak a English?

Well, if it's just a problem with English, then take the time to write and speak it more carefully. For example "im" doesn't exist in English... we only use "I'm". It's very easy to avoid little errors like this. :) I can't know for sure, but I wonder if your shyness and negative feelings are also obvious to the people at your work. For a start, just smile a bit more and focus on the work, or try to be helpful. See if that works for you. Or, your work colleagues are just unfriendly. ;) That's also a possibility!
