Welcome to the forum LinzAy and thank you for sharing! Don't worry about being too quiet, I used to be that way when I was younger, used to drive my mother mad but as one other quiet person said "no point in speaking til you have something to say" I think when you don't say too much, then what you do say is far more precious than those who prattle on constantly!
I talk more now but perhaps I have more experiences to share than when I was younger.....and a bit more confidence.
You're fine as youare!
