I can completely relate actually.  I have been in a depression for about eight years and I am for the most part in recovery right now.  Although most of my problems result from some events from my childhood which I would rater not release right now.  I have also always had problems with feeling like I don't fit in with society on several levels and although I don't like to admit it this does hurt.  But a few years ago I did find a friend who really did seem to understand me at first and then later I was back-stabbed by this friend.  When this happened it almost killed me on the inside and I really don't know if he knew knew it felt for me to be accepted fully for what seemed to be the first time and to be thrown away later.  Then after this I dated a boy who tried to change me into something else and since I ad never felt accepted this lost me even more.  With all of this behind me I remember crying myself to sleep very often and one attempt that I now regret.  But on the Bright side of all this I ave been inspired by many people close to me and even some others and I have also seen a few doctors who shown me ways out of this.  These people still help me to get out of these situations and if I could help anyone else I would love to do so.
