If you find someone you can trust in the day-to-day environment, I have a hunch you could benefit greatly if you could confide this to someone. It could be "your friend you don't talk to" and both would know it's because you don't like talking much.

I don't recommend having only one such person if you have depression or anxiety. Things can go poorly should things ever go sour with a small number (~1) of trusted friends.

And of course a network of friends while helpful is not a 1-for-1 substitute for say, a therapist.
