I'm sorry to know that you are facing some problem. It's naturally for someone to meet with different kinds of problems when he first studied abroad. The language problem is the first one. But I'm sure you'll soon be able to use the language well, so I know you're a quick learner. Being sure to take every possible chance to practise your oral English, that will do good to you. The second problem is usually the change of eating habits. Not everyone can get use to a different diet, so why not to cook meals by yourself? Studying abroad is big challenge to you, but it's really interested.
