Hello, over the last few years I have gone through long periods of depression which i feel i have never really been rid of and i am feeling depressed again. I'm not really sure what the underlining reason is for my depression though. It could be low self-esteem and self confidence but i'm not sure, i feel this just contributes towards it. I don't really know why i feel this way though, i have good grades and am doing well at college, i am told that i am good-looking and i'm also good at sports, but i can be extremely shy, and because of this try to avoid contact with some people. In the past i've felt depressed to the point where i have contemplated getting help from a doctor but have never had the courage because i'm scared that there is actually something wrong with me. I used to have strange thoughts of something bad happening to me or someone close to me which scared me, and i hated it, I've started to have similar thoughts but not as bad, I just want to know what all this means?
