best books I could recommend are fiction, they teach you much more than non-fiction, lessons learned in stories are better tha unordered lists of advice you'll forget in a few days.

Some of my favorites include: a moveable feast, watership down, 11.22.63

I remember how lost when I was 16, truly it was just a massive wave of depression and fear and loss. I encourage you to do what I did and explore as many facets as you can possibly imagine (coding, guitar practice, drawing, 3D modeling, pixel art, car tuning, botany, gardening, astronomy...) and if you find something you love and you find yourself doing it for months almost like second nature, you should follow that in whichever career direction it leads you or wherever it takes you with school and opportunities.

There's no one set path, and I did struggle with that as a 16 year old as some paths appear better than others. In my time, html, css, and js bootcamps were literally everywhere and now, look at the development space. you never know and you can never predict the future, but you can follow what you love and opportunity will present itself for you to shine and feel comfortable.
