Dale Carnegies book 'How to Win Friends and Influence People' could actually help a bit. It's a self-help book, 100 years old, but still very relevant. Nothing magical in it, but quite useful, and for somebody as young as you are it could have a big impact over the lifetime.

In any case, just know that a lot of people struggle with it - much much more than you could imagine. It's worth trying to fix it though.

Good luck !
