Tips and Advice for a Newcomer to NoFap

Im a muslim 15yr old boy and found out about porn when I was 12 and a bit. Most people at school and on the internet say that watching porn is normal and that they do it every week, i know its bad but i do it anyway.
I have always tried many times to get in control of my life and delete porn from my life.
I spend a lot a time on the internet because I'm not allowed to go out with friends because 'It's too dangerous'.
I feel awkward around external family parties because I think I'm the only one like this.It's only then I also feel shy when I'm talking to girls i like
My parents think I'm innocent and still a little kid which makes me feel like I'm living a double life
Before i signed up to NoFap, my highest streak was 11 DAYS and that was when i had network issues.
I don't find it too hard to not masterbuate for a week but porn is the main problem.
What makes the situation 10x worse is the instant guilt and remorse i feel after i realise what i did and that i have to clean myself.
I'm honestly trying to change my ways and communicate more confidently to people instead of being the 'quiet one at the back of the class'.
I've also heard that masterbuation to porn rewires the brain of a teenager so it stays with them and finds it hard to function without it and that it stunts the growth because the sperm thats leaves the body consists of vitamins and things necessary for growth.Can you guys verify this?
Don't judge guys.

 

For some reason i want to be tall and big when i grow up like the rest of my family and not to be lacking of size when compared to them. If it's true it makes me more motivated to quit.
