Recommend going vegan?

i'm 15 and have been a vegetarian nearly a year, i am unsure whether or not to become vegan. i am used to eating quorn as a meat substitute but it contains eggs, so i would no longer be able to eat this. in relation to health would vegan be better, or should i just stay vegetarian? any websites you know for 'new vegans' or anything like that would be really helpful!
