Work can be scary. I worked a high pressure teaching position for twelve years. Many days I felt like I didn't deserve what I had earned through all my hard work. And then I went on a manic rage when my department was being cut to 30% and it was all over. I started my own company shortly after (talk about scary!)and although I struggle (bipolar disorder) daily, we have been open almost three years. Do I get scared from time to time, hell yeah, but its on my own terms, not some group of bean counters with no perception of reality. Fast food probably just isn't for you. Don't give up.
