Sharplin this is exactly what I went through only I've come full circle again. You will too. Work on inner game and start building real confidence and not fake confidence. Like Jav says, love yourself, and start building up your life.
My thread "How much do you respect yourself?" was actually aimed at people like you, people who kid themselves that they have value but they really don't. People who take PUA too seriously. People who are blindly arrogant that if a girl doesn't like them then there is something wrong with the girl.
It's only when you start to question yourself do you begin to change. I grew up very underconfident but when I started Sixth Form I made a good set of mates, I became more confident and my true funny personality came out. I started to pull girls, I became even more confident, which as a result led me to pull even more girls and turning my confidence into arrogance. I lost friends and lost a great girl and only began to realise what a dick I was when I was told I was a big headed prick.
Then I read The Game and found the community and became even worse. All of a sudden I had an even bigger advantage on most guys. I knew how to flip attraction switches and connect with girls in a big way, except this was fake connection. It was connecting to get into her, not a genuine one. However I came full circle.
You've realised something similar, now all you have to do is change. Start looking out for others more and be sociable simply even to make someone's day better. If you meet new people, take a genuine interest in them and people will love you. If you see someone sat on their own in class or something give them a smile and a hey. Friendliness costs nothing.
I believe this post by Johnny Soporno will help you greatly, please read it.

Go into 'classic writing' and read 'A definition of inner game...'.
If you have any questions ask me, because I believe I've been where you are before.
