I was the same way ,I didn't want to tell anyone about wetting the bed, because of that reason. It is ok not to tell anyone as long as you don't show or reveal it. I think it's cool to have 3 sisters that look like you. I am an amputee so I aslo get made fun of for that ,because everyone knows,but I am not saying you should or should not tell anyone, it is all up to you and your mom and dad. God bless and have fun through life. And finish school!
