Is it normal that i'm 22 and terrified of never making it?

I'm only 22 (shortly to turn 23) and I'm already terrified that I will never make it in life. So far I've done well in education and have a degree and a postgrad degree to my name but I am really struggling to break into documentary filmmaking, the career of my dreams. Wherever I look people my age are better qualified than me with more skills and experience. I have been working for peanuts for well over a year now but still haven't got anywhere and it's starting to get me down. All my friends are extremely successful and I'm terrified of being left behind. I am probably too young to feel like a failure but that doesn't change the fact that I do.
