You may need to take some time to address your particular situation by first talking it over with a trusted friend. Perhaps you may come to the point of needing to take some time off from school or withdrawing from one of your classes. It's generally not advisable to make hasty decisions but to explore a number of possibilities with the assistance of some other people. There are some people around campus who may be helpful to you. Since your usual support system and ways of coping with problems may not be available to you, it might be helpful to know who might be able to help you while being away from home.
Services are free and confidential.
You may want to bring a friend along to feel more comfortable. Specific preparation is always very helpful. Certainly the hope is that nothing difficult will happen especially while you are separated from your family. Things will take care of themselves later. It is very sad when it is too late.
