If one have clinical depression you need professional help. While it is always great to focus on the good things in life and all one has to be thankful for, the clinically depressed person simply can not do it. That is part of what clinical depression is: the inability to appreciate the good things or how much better off you are than others. The clinically depressed person may be able to understand intellectually that they are better off than others and that there are good things in life that they could focus on. But they cannot feel it. It's kind of like if you eat food but never feel full or even half full or even in any way satisfied about the food you ate. You just don't feel the goodness in your life no matter how much there is. Focusing on it may help those who are not clinically depressed. Everyone should try that. But if that doesn't work, if nothing in your life gives you a sense of accomplishment or belonging, and that lack of feeling does not go away every for a significant period of time, you need professional help.
I just read yesterday that there is a strong link between depression and anger. It stated that depression is anger turned inwards. I find that to be true for myself, when I am frustrated/ angry over a large issue that seemingly has no resolution, I begin to feel depressed. Could that be the case with you?
Ok these answers are pretty terrible. I've been going through an off and on depression lately and there's no way to just get rid of it. If you think you might have depression take an online test and if it says that you do, then you should go take a real test from a doctor. Depending on how bad your depression is and if you are suicidal or not, the doctor will decide what's best for you.. He might send you to a therapist or to the hospital.
Talk to your parents or someone you trust. Depression isn't a joke.
If you have not been diagnosed as being clinically depressed, healthy exercise, helping others (volunteering), if you like animals go visit some animals at the SPCA, hang out with friends. Pretty much anything that allows you to quit thinking about yourself so much. And know that this is just a passing phase.
When I was 13 I came down with a number of anxiety disorders. One of them was agoraphobia (fear of being outdoors) so I stayed inside. For most of my time, even indoors, I couldn't escape my anxiety attacks. The mix of almost never being outside and always being attacked by fear led to a number of emotional disorders, which led to a lack of ability to socialize, which led to loneliness, selfishness, depression, and what seemed like a conduct disorder. By that time I was so mentally fatigued that I couldn't think properly. I can't explain how, but somehow my view of the earth, society and existence was disordered. I just couldn't think properly. My home/family life was fine but my mental life was horrible. I never had relief from fear, sadness, and hurt feelings (because I was overly sensitive). Then one day when I was 15, a girl I was obsessedly attached to began to hate me so much—due to my selfishness and oddness—she told me she hoped I would die somehow. This hurt me severely, but it caused something in my head to click. I caught a sense of realism, maybe because it was the first time in years that I was hurt by something other than myself. .
