Is it normal to be scared of talking?

It's not normal, but I definitely relate. My advice would be to push yourself a little each day to say something in class and then soon you'll feel more comfortable and won't be so nervous. I know it's hard, but good luck!

Yes definitely normal, to the max! You just described me or at least how I used to be in HS. Don't get me wrong, I still am not a confident put myself out there person but I'm more confident now. I can definitely relate with the pee thing, especially when the class is quiet hahas and I get red easily but girls think its cute! Not too red though, just like cheeks flushing. Also, I get so flustered I say things and I don't even know what came outta my mouth! I like you because you're like me :] I used to perform so badly when though during practice I'm top notch, just train your mind the most to shut things out and keep things in. Visualizing scenes of perfection help, and professional athletes do this, so you can do this for music. Um on little thing, I used to have braces so that made me super-shy to open my mouth hahas so with it gone, I feel more confident to smile and smiling makes nervousness go away in my case :]

I'm like that too :/ it's basically just being afraid to talk in public. It's a fear called Glossophobia.

when i was a kid i was really quiet u could not make me talk but i learned how are u going to get a job if u don't talk so here i am talking well writing andi hope my advice works

I was like that too, same exact thing, I would never raise my hand but if I were called on, blush and say "I don't know" because my mind went blank whenever I was expected to talk. I have social Phobia and I'm on a medication for it now that helps along with practice, which I never believed, because I was too scared to try, but you just have to start out slowly and don't give up. Many people have that and either get help or grow out of it...

maybe selective mutism.
you should
look into
it, read about it and ask
or help. there is lots out there for people
like us! texting electronic communication is very helpful for
us these days.
good luck!

Are you afraid of other things?

i am the same except you know when i want people to feel foolish by by answering several questions and being right before they can

Damn! I hit "no", mentally take it out and add a "yes".

I do this too. It's too stressful for me to go out and be around lots of people. I'll barely be able to talk much less admit that I have to use the loo. I use to go to summer camp and I would hold myself because I was too scared to admit that I needed to go to the bathroom. Eventually, I learned to train myself not go at all and only go when I got back home. Others did it too, but it probably wasn't due to a "phobia". When it comes to talking I'll become mute/selectively mute. Sometimes, I haven't been able to say anything for days and what comes out is usually a barely audible whisper.
