What do I do at this age about therapy?

As the title says, what do I do about therapy?

Recently turned 14 y/o (ninth grade though I entered school early), and I want to go to therapy, want to try and better myself, but I'm not sure at this age, considering that my family is very nosy and my classmates downright anti-privacy-that-isn't-theirs, and I'm scared that I might freak out if I'm assaulted by enough questions, and I'm afraid that too many questions might be asked by too many people.

That, and I'm afraid in general.

So I need to ask, until I can go on my own and get therapy (if I can pay 😭), what do I do at this age?
