I've been feeling depressed for the past few years and its gotten worse. It's not like I feel depressed everyday to the point where I am sluggish and unfocused. Sometimes I feel happy or most of the time it's just okay. Most times I feel depressed in general about my life. I am not happy at all. I can't find any form of happiness not even my friends and family. I've never seen the point of living my life, I'm just living just to see how the world turns out, not even for myself. When i get these periodic depressions I get the symptoms of what a person with depression would have like loss of appetite, sluggish, unfocused, loss of things I used to enjoy. This also comes randomly and I can't predict it, even sometimes it comes when I am in big crowded places with lots going on, when it comes I just leave and lock myself in the bathroom till the tears go away. I've cut myself before and am considering to do it now. Today I woke up crying. I don't know what's wrong with me. Is this depression?
