voice problem, HEEELP ! Pleasee help me. Options

[demolished]

I have a problem with my voice, vocal cord or whatever.

My voice (sounds) started to shrink ever since I was sick and cold. (Last year)
My sickness lasted about 2-4 weeks ? I dont know.

Now, my voice still sounds the same when I was sick.
How come my voice wasn’t cure?
It’s been about a year already.
I’m 14 years old. I don’t think it’s something to do with puberty.

Btw, i use to have a loud voice. I could even change my voice pretty well. This time, i cant do it anymore.

more infomation and details are posted below.

What words can you not say?
I use to not be able to say certain words so I practiced saying it (enuciating?) it and i got better..it also helped my friend who had a accent..(It was for Drama..)
Well try say this:(very slowing)
Red leather, yellow leather
copper kettle, brittle brattle
scadeliy dee, scadeliy doo..
Say each vowel/consanent out loud and tape it, and then try to improve how you've said it..It should take about 14 seconds to say the whole thing..
Sorry if this didn't really help..

There are many words that I cannot say such as carrot, familiar, dog, and sleeping. How cool, I took drama class last year. It did improve my screaming ability. Before sickness, I could scream awfully nice but now, it's still horrible (even though I took drama class).

Amazing, my formal drama teacher use that similar voice exercise method but it's was actually longer. Would you like to type it up some more? I forgot the how to do the voice exercise method from my teacher.

Be careful with hot drinks, because if they're too hot they're actually bad for you. Try doing voice exercises, ask a voice teacher! oh yea..and puberty.....give it time 

Yeah, I usually let my hot chocolate to get warm a bit. I even add ice into hot chocolate to reduce waiting time. But, I don’t know why hot drink is actually bad for me. It'll mess up my tongue or what? ..About the voice teacher? I don’t have a voice teacher or know anyone of them in my recent high school (I’m a freshmen) ... puberty? How could it possibly cause by puberty? My voice changes before and after sickness. It was working well before I have the sickness.

You have to go through surgery, I can't beleive you have never heard of it. They have it on kids cartoons all the time. They go through surgery and get their tonsils removed, they stay a day in the hospital, but they get all the ice cream they want! (In reality, you can only have sherbert for the first 24 hours, that way you don't throw up.)

haha i don’t know. I finally know what it looks like when I use yahoo image search engine. ekk, I don’t want to go to the hospital. it's too much like ..
