I felt like that for many years, luckily in my late 20's I got what I thought I could never have - which I always thought was to be liked by others, or to be normal; I realized later it was to be liked by myself.
Once I started to appreciate myself, life got much better and is now great. I'm still not normal but I revel in my oddness. I still can't emotionaly connect like a normal person, but I accept it and sit happily on the outside. I still go through mania and depression, but now I recognize the phases for what they are and know that they are temporary, and since I stopped partying I am ten times more level headed than ever before.
It's hard to believe it myself - but I went from being too much of a wimp to kill myself in my younger days to really enjoying life today (and for the last 8 years or so). Now I have a wife and a kid on the way.
My self image went from way below zero to pretty good, then I got semi-disfigured (nothing really major but enough to knock me off my high - in more ways than one) and settled to pretty good, but self conscious. And glad to have my minor issues over the real issues I could have.
Anyway - yes, but luckily not anymore.
