Grose My family wanted me home every other weekend, but I didn’t fit in there anymore. I’d argue constantly with my father, who still treated me like a child. My sister thought I was "uppity". Everyone was miserable, and I felt guilty. I decided to try treatment when my friends got fed up with me. They didn’t want to talk about my problems any more, but my problems were the major focus of my life. I needed someone who could help me understand what was happening to me. I’d seen ads for the counseling center and decided to give it a try. Kwanzaa When I took a part-time job and started living off-campus, my course work fell apart. I couldn’t concentrate or sleep, and I was always irritable and angry. When I began considering suicide, I knew I needed serious help. My resident advisor helped me call a local hotline where I got some good referrals. It was just a phone call, but it was the starting point that got me to the professional help I needed. Cheever I’ve always been anxious and never had much confidence. College was harder than I had expected, and then my parents divorced, which was traumatic for me. After a while, all I did was cry, sleep, and feel waves of panic. Actually while the depression was painful, working to get better has taught me a lot about who I am and how to stay healthy. Colbert After two years, of straight A’s, I couldn’t finish assignments anymore. I felt exhausted but couldn’t sleep, and drank a lot. I couldn’t enjoy life like my friends did anymore. I kept asking myself, "How could I be depressed I’d had a normal family life, had been getting good grades, and hadn’t experienced any big trauma—where did my depression come from" I knew I was depressed but thought I could pull out of it by myself. Unfortunately, friends reinforced this attitude by telling me to just toughen up. When that didn’t work, I felt even worse because I had "failed" again. When a friend suggested I talk to his counselor, I resisted at first. In my mind, professional help was for weak, messed up people. But then, I hit a bottom so low that I was willing to try anything. Getting treatment definitely changed my life for the better and helped me avoid flunking a semester. Fenty During a manic episode, I stayed awake for five days straight, but had a lot of energy. I spent my tuition money on a major shopping spree (购物狂欢) and long distance phone calls. I also played around with several guys that I hardly knew. At the time, I felt so great that I couldn’t see that there were serious problems with what I was doing. Now that I’ve gotten some treatment, I’m back from the edge, I know how to keep from being out there again. Now match each of the people (61 to 65) to the appropriate statement. Note: There are two extra statements. Statements [A] I never changed the opinion that professional help was for weak, messed up people. [B] Getting professional treatment can really pull me out of depression. [C] At first I didn’t know where my depression came from and resisted professional help. [D] When my friends were impatient with me, I decided to go to the counseling center for help. [E] A phone call got me to the professional help. [F] Everyone can be full of energy for five days without sleep. [G] I learned a lot about myself and to stay healthy through the way of working to get better.
