Thank you for being honest about your age, Haseeb. I've read your posts on the UF forum and you seem like a nice guy, willing to help out and caring about others. However, 12 is way, way, too young to be joining VU. It's probably too young to be playing this game. Thank you for your interest in VU, but I am voting no, and will continue to do so if you apply again, for at least another three years.
I remember how shit it was to hear the phrase 'Sorry you're too young' when I was your age. Sadly I can't help that. What I will say, is that you shouldn't be sad about this. Sometimes we get to choose what makes us sad, and this is one of those times. Being in VU is not that big of a deal, it's just a group of people who like to play a game together. This group is fun, but becoming a member of it will not really change your life, and nor will it bring you lasting happiness. So you can choose to be sad, or you can choose not to be sad, given that this is not as big a deal as you seem to think it is.
