In Brief:
Depression is a common problem for college students. For Christian students, moving away from their families likely means moving away from their church as well, so they may feel particularly isolated, especially when they have moral objections to certain risky behaviors that may be common in their dorms. Fortunately, help for a depressed Christian college student is not hard to find! Most campuses will be home to at least one Christian student group; seeking out this group, you'll be able to talk to a peer, someone who understands both your background and the challenges that you face as a student. Any church in the area will likely be more than happy to provide help for depressed Christian college students (or anyone else, for that matter); you can probably find contact information on the web, or just walk in and make an appointment.
