In high school, I was skinny and had a soft, squeaky voice. I went from Catholic school to public high school, so I was a new kid. I had only a few friends. I thought maybe I could have had better years there because at various times I would make a comment that my friend would hear, he would repeat it much louder and got lots of laughs. Kind of like a prehistoric repost!!! I figured if people would hear what I had to say they might laugh, and realize I had no hostility towards them. Luckily, most of what I had to endure was verbal.
I have a stronger, deeper voice now and lost most of my shyness.
Glad you are doing better :-)
