Life in UK is quite different from India and expensive also. It is actually hard to move in a different country and lead a totally different life. It gets even tougher if you are visiting for the first time. It takes time to get along with the situation but it can be managed.
Almost all the student experience this when they arrive in UK. The language, food and behavior may seem different and strange compared to what you are used to at India.
Remember that you are not alone. Talk to other international students who are probably going through the same thing. Take along a few items from India with you to make your room/space feel more like home.
But on the plus side, there is a large Indian community in UK, and as a student there will likely be many university groups where Indians get together regularly.
