I have the same feeling...I also doubt whether to go back home. However, US is absolutely different from China, and we should not transplant past experience to the new life here. Once I was thinking about giving up. If I stayed at home, I would be able to work in a small local bank , live a comfortable life and stay with my mum and dad. What a happy life it would be! Before I left home, I was eager to see the world outside; after I leave home, I find that life is never a piece of cake. I believe things will get better after you adapt to the environment here. Hold on to see what will happen.
