I Need Help. I Can't Go on With This.

I Need Help. I Can't Go on With This. I have had a stuttering issue since I I first started talking. I was able to keep this under control for most of my life so far (I'm a sophomore in highschool). Last year I felt like I had it down real well, almost no speech problems but then this school year started. In Spanish the teacher asked me to simply say 'hola' and I completely froze, couldn't get a single word out. It was even worse in history, I had to get up in front of the class and read. I stood there like a frozen human popsicle, not capable of moving my mouth or saying a single word out loud. I couldn't even tell my teacher my grade, that one caused me to get some stares. I have to take speech for college credit and of course Spanish, both of these classes are depending on my speaking fluently but I can't do it. If I speak to my self or friends I have no problem, it's as soon as I'm put in front of crowd, that when I freeze. Which leads me to think this has alot to do with social anxiety. Even if I take care of the anxiety I will still be stuttering. I need help getting stuttering out of my life and hopefully anxiety with it. I'm willing to do whatever it takes.
