I found that hypnotherapy CDs helped increase my confidence a little - you can download some of these online for free.
I used to be on anti-depressants (Citalopram) for a few years, which really helped to take the edge off my anxiety at first. I was pretty much mute (in public) at age 16, but after starting the medication I was able to speak almost normally in some situations.
If you can't talk to a GP, talking to your school counselor might be a good idea. If nothing else, it will be a good challenge for you to express your feelings out loud and confront some of your anxiety.
