I WANT TO LEARN CODING...PLEASE HELP!!

I am interested in coding but i have no idea where to start...I am interested in web development, encryption, cyber security and game development (is this too much?) but i am totally clueless on where to begin. I have tried codecademy for HTML but it felt like i was dropped in the deep end with neither a float or an inkling of what to do.

Where do i start and is there any basics i need to know before starting?
