My advice is to make sure you don't get depressed or hopeless. Being away from home for an extended period of time and adjusting to many new situations can lead to a negative impact on mental health. Both depression and hopelessness happened to me in college, leading to bad results (I didn't date, I had no friends, I didn't care about classes since I thought everyone in the world was going to die from pandemics/war/etc). If you find yourself becoming depressed, the techniques at the following link may help. They're based on empirical evidence and have helped many people: http://bit.ly/z8rwF
