The lost decade of my Life

I am 22 year old guy and there is not a single day in my life without P & M. I am doing it since I was in my 8th Grade i.e. around 13 years of age. I wasted almost a decade of my life(whole teenager phase) to pornography and masturbation. I found it so much satisfying that I used masturbate till ejaculation atleast 2-3 times a day at that age. Although I think my body was not prepared for all this at that time as my orgasm ended with sharp head pain and elevated heart beat but that doesn't stop me from doing so and after few weeks my body got accustomed to it. Since then I became so much addicted to porn that i started finding ways to avoid my parents and friends to get some alone time so that I can watch porn and masturbate in peace. Earlier i was unaware about the consequences but with time I realised that the thing that I am riding with is the Devil himself. My whole life is devastated due to this bad habit. My current status:
It is very difficult for me to concentrate in my academics which is the need of the hour as I am in the crucial stage of career building.
I want to join Army but I can't as I have weak eye sight due to excessive masturbation and kyphosis due to low self confidence.
I have no goal, ambition or motivation in my life till now.
Next month Iam going to be 23 and i have never had a girlfriend or sexual encounter in my life although Iam good looking but I never gathered enough courage and confidence to talk to a girl even after knowing that she is also interested in me because of my introvert nature. I saw the girl I love taken by another guy in front of my eyes.
I spend most of my time alone in my room with my Smartphone and Laptop. In meantime worring about myself and doing nothing about it is a usual thing. I find it very difficult to mix up with other people.
Even though i have good physique and also a reasonable person but whenever a diptute occurs I prefer flight over fight.
Everyone thinks Iam nice, sincere, gentle and disciplined but deep down I know that Iam not even close to it.
98% of my interest data is watsed on porn sites.
Success is an unprecedented word for me.
I consider myself as a totally wasted guy.
And yes I blame pornography and masturbation for all this because all the productive time of my teenage and adulthood is wasted on this addiction. But now enough is enough. Iam fed up with all this.Its time for me to rise from ashes and that's why Iam here and I need your support.
Pardon me for my poor English as it's not my native language.
