Job Jitters

SO today is my first day of training at my new job. I am so excited but also so nervous I could throw up. See for a long time I have felt like a failure, and it probably comes from some traumatic childhood experience, that I cant ever fix. So anyway I keep thinking I am going to screw up, that I can't do this. I'm terrified because what if I am right? Worse yet, what if I am wrong? The lie of my life being a failure will be shattered, will I put back the pieces to hold on to my reality or will I say good riddance you evil thought? Just first day job jitters, I wonder how my buddy ,formerly known as a bum, Kevin's first night on the job went? I'm curious to find out, I guess I wont unless he emails me cuz I will be at work when he wakes up and he will be at work when I come home and then I will be asleep when he comes home. Its a mess. A job change can be very stressful. I have been a photographer for several years now, what if I don't know how to do anything else. Yesterday I almost answered the phone "Skears portrait studio, this is Rebekah, can I set up an appointment for you?" But then I realized I was at home. I guess that's what happens when you work too much (8 days straight) and your company uses you, so I will be happy for the change, but its still a change none-the-less.
