DiDi--I didn't know whether you realized that the other posts are from over a year ago. But I'll try to give you some help if I may.
It's hard enough being away from home for the first time and you throw in that you're in your freshman year, then it's doubly tough. Trying to connect with people and speaking a another language is the triple whammy! I can't see how you wouldn't feel depressed and have panic attacks at times.
You left behind a comfortable lifestyle with your family and friends. Now, you are starting another phase in becoming an adult. If it's any consolation, many freshmen have problems adjusting to the disorienting first taste of college.
I have three degrees, which means I spent a lot of time on campuses and I guarantee it gets better, as you decide what courses interest you. Also, try to make just one friend first. Pick someone out in class or in your dorm and make sure they know english. Take the initiative and start a conversation and try to seek out people with your interests. Just one friends leads to other friends, etc.
If you need to transfer to a school closer to home, then do it. Listen to what your brain tells you to do and do it. Whatever is best for you and your studies. It's important that you are in a better frame of mind to tackle college, so make yourself happy. Good luck.
