Well, if you left behind a significant other whether s/he is still in your hometown or at another school, you will miss each other. Try to accept that fact first. If you dwell on it, it will be harder to deal with and may adversely affect your schoolwork. Next, try an arrange occasional visits if the distance doesn’t prohibit it. Talk on the phone and send e-mail. If the relationship is equally important to both of you, it may last through 4 years. Keep in mind, however, that most high school relationships don’t last. Spend a lot of time making new friends and getting involved in activities. First, it will give you something to share with your loved one and in the event the relationship falls apart, will give you a support system to fall back on.
