I am asking personal help, what is dragging me back?

Recently had an interview in which I didn't gave my 100 percent, it was failure but I am not new to it. But this time something different happened I was shaking from inside, and negative thoughts about myself were coming spontaneously even if I didn't want them. It seems like I am not able to live upto my full potential. Something is dragging me from inside, what is it? Is this explained in Buddhism? Is there any name to this condition?
