Is it normal to feel dread before starting a faculty position? I need some advice. After several months of interviews and work, I secured a faculty position at a good business school, which was a relief since jobs are so hard to get around here. Everyone tells me I'm lucky to get such a good job since I'm coming right out of grad school.

It's been about two months since I took the job, and I've started to receive teaching allocations etc for the coming semester. I should be really excited and happy about all of this, but instead, every time I think about starting this new job, instead of excitement I just feel awful: afraid, nervous, like I'm making a huge mistake and I want to cry. I can't figure out why. I feel like I'm supposed to want this and I just don't feel positive about it. I worked so so hard to earn it but now it doesn't feel like a prize. I just have this overwhelming sense that I'm going to be absolutely miserable. I don't know if it's just about the B-school thing, or academia in general, or just because I'm nervous about being a real adult for the first time, or because I know people who have had a hard time with teaching etc, but I'm confused that I can't tell these apart.

Am I naive for thinking that I should be excited and overjoyed about this job? Does it mean I'm a normal academic that I feel dread, or a terrible academic that I don't see it as an opportunity (besides the great salary)? Does it just make me a privileged a-hole that I'm expecting to feel joy but I don't? I would appreciate any words of advice, your experience with before job jitters/dread and whether it gets better or whether I may be making a huge mistake? So confused!
It's perfectly normal to feel the way you do. Part of it is likely fear of the unknown; part is fear of a new job with "adult" responsibilities; part of it might even be fear about whether you can do the job (the infamous Imposter Syndrome). Transitions are always a stressful time, and I don't think we give ourselves enough time to adjust. 

This also reminds me of a survey that discovered that people who just got tenure are the unhappiest of all faculty. The similarity is in the striving for a prize that's difficult to get, and then getting it ! In both cases, there's an element of letdown, and "I did all this work for THIS ?" 

One technique that I've found useful when dealing with these kinds of feelings is to try and focus on the concrete rather than the bigger picture: in your case, maybe focusing on logistics issues related to the transition rather than the bigger picture. 

I've also found as a rule of thumb (both personally and with others) that it can take upto 6 months to feel some level of comfort in a new position. That's a long time.
