Holy smokes! You are gorgeous in all your pictures!
I can relate with you on the confidence thing. I am always told I am very young looking (I am 33 years old) and good looking, but for some reason I have been single for the longest time. I know it has a lot to do with how my confidence issues project on others. It's like I was an 8, but with my attitude I turn into a 4 or a 5. But I am in therapy though! I have always been the quiet type, and never really just walk up to women to ask them out or whatever. I am always afraid of what people think of me.
So you aren't the only one with confidence issues.. Bottom line though, you are gorgeous. I am sure you have no problem with people telling you that
