Graduating Soon

I'm about four months from completing my Master's degree and I'm excited for that. Grad school has been stressful and has definitely not helped with my anxiety. However, I am anxious over the thought of applying for a job and actually needed to work for a living. Don't get me wrong, I've worked consistently since high school, but there's a difference between working at a fast food restaurant part time so that I have money to eat, and working full-time so that I have money to live. It's like I've been stuck in this in-between phase, not an adult, but not a kid either and now, I have to be a full-blown adult here in a few months. There's going to be no more tests or research papers or office hours. Part of me is excited for this, since it's something I've never experienced before. Another part of me is worried that I'll fail because the only thing I've had to do well these past few years was simply not fail at school. Then there's the whole thing about applying for these jobs and I am not looking forward to that.
