_____ (1) Today, I'm grateful to my college for wanting to help people like me, and I urge anyone who is feeling depressed to find out more about his or her college's resources. (2) Students shouldn't go on floundering until they drown, not when there are people ready to toss out a life preserver and pull them in to safety.
_____ (3) I got this help by visiting my college's student health service. (4) Like many colleges, the one I attended had beefed up its resources for students who are having trouble coping with their new challenges. (5) I was able to take advantage of free on-campus counseling with a qualified therapist named Becky. (6) I told her how I felt, and she helped me figure out how to deal more effectively with the stress I was under. (7) I learned, for example, about how to use time management and exercise to better cope with everything I had to do. (8) Before long, I felt the cloud I had been under begin to lift. (9) I was still busy, but I didn't feel as overwhelmed, and my grades improved from Cs and Ds to As and Bs.
_____ (10) Second, I found out that my feelings were fairly common. (11) I searched for information online and found out that, according to an American College Health Association study, 10 percent of college students had been diagnosed with depression. (12) In addition, the National Mental Health Association reports that one-third of all college freshmen say they feel overwhelmed a great deal of the time. (13) It was a relief to discover that I wasn't alone. (14) Knowing that encouraged me to take the next step and get the help I needed.
_____ (15) The first thing I did was admit to myself that I was depressed. (16) One day while sitting in one of the student lounges on campus, I picked up a pamphlet published by my college's student health service. (17) It included a list of questions, such as "Do you often feel sad, anxious, or empty?" "Do you often feel fatigued or low in energy?" "Do you have difficulty concentrating or making decisions?" (18) I was surprised when I found myself answering yes to almost every one of these questions. (19) Since then, I've found out that most colleges are trying to educate students about the signs and symptoms of depression and other mental illnesses. (20) Through information posted on college web sites; printed materials like pamphlets and posters; and even forums followed by free screenings for eating disorders, alcoholism, and anxiety, colleges are helping students like me recognize when they are battling a very serious problem.
_____ (21) When I first started college, I was excited and happy. (22) It wasn't long, though, before I began to feel overwhelmed. (23) I could barely keep up with all of the assignments, tests, and papers of five different challenging classes. (24) At the same time, I was in an unfamiliar new environment, homesick for my family and friends back home. (25) After a while, I wasn't handling the pressures well at all; in fact, it was all I could do to get myself out of bed every morning. (26) Fortunately, though, I was able to take positive steps to identify and solve my problem.
