An awful period

It has been 5 months from the first day I came back Vietnam from Taiwan. I have got the job in Foxconn, I am the member of Project Management team. My responsibility is handling every thing related to cost, price and contacting with customers about any problems happened. But It is really a bad life that I have never ever lived. I met a lot of people whose characteristics made me crazy. At the begining, I went there with the full of energy, the hope that I can improve myself, can learn many things from outstanding colleagues, and My chinese as well as English will be better as much as possible as well. But I am totally wrong. What I got from here is all of sadness and stress. Noone taught me, everday I went to office just sat and saw people do their own tasks. I even did not know what I am doing. What I am fighting for. But it was not the worst thing that I want to mention. I met one boy who is the same age with me. Although I had no impression about him, I even did not know who he is until the day we had a dinner together, of course with our friends. And one day, when my sister was busy and let only two of us go to eat outside, he was angry. Now I know why did his behavior like that, because he didnot want to go with me. But I thought he did hope we have a date once in our life. I was wrong from beginning. And next time, I invited him go to see a movie with me, since Deadpool 2 was released earlier than expected. I has been waiting for such a wonderful movie for few years and This time I finally had a chance to make my dream come true. He said he would arrange his plan and we could go there. But after all, the next part made me down, it was not as exciting as I hoped, and he also kicked a big ball on my mood when he asked to come back right after it finished without watching after-credit as Marvel's Fan always do. And he suddenly kept me at a distance and did not chat with me much like before. I felt I was kicked by a very painful way. He threw a cold water on me. I was a loser. I was really lonely in Foxconn. No one came to comfort me, they juat want to criticise me that I just like a kid, my thinking is not mature enough. How can I overcome this time! HELP ME!
