Help me out of this inferiority complex!!!!?

Your focusing too much on the way you felt in high school. High school popularity is stupid and it doesn't mean anything if you weren't popular. Concentrate on getting good grades in school and you will make something of yourself which in turn will boost your confidence level. People who were popular in high school find it difficult in the real world because they are not the centre of attention anymore. Trust me, things will get better and you will meet nice, normal people. Not people with labels, ie jocks, preps, stoners etc.
