Doom II

I realized that I didn't fail the permit exam because I'm dumb, I failed it because I lack confidence. I got a total of 4 questions wrong (the maximum number of questions you can get wrong is 3). I knew the correct answer to 3 of those 4 questions but doubted myself. I think this feeling has to be more frustrating then not knowing the right answer. I don't know why or even how I've gotten like this. I think I always used to doubt myself to some degree but this is unreal. I've let my lack of self confidence control me. The reason why I'm having such a hard time applying for jobs is because I don't think I can get them. This must end!! But how...
