This week's search terms bringing people to this blog ... now with commentary!
"guilt about leaving academia"
Why be guilty? Do you think your department feels guilty that you're so miserable that you want to leave? I doubt it. There's nothing to feel guilty about if you are miserable at your job and want to leave. As long as you leave in a respectful way (don't abruptly quit in the middle of a class session, notify your advisors, don't burn down the building on the way out), why should you feel guilty? Your department will go on without you. You can still find ways to teach and do research. Don't feel guilty for making yourself happy.
"about to begin graduate school, depressed about money"
It remains to be seen if you will have enough money to survive on. But there's nothing wrong with wanting to make enough money to survive. Grad school can make that very hard. There's nothing wrong with admitting that, or with doing something to make your financial situation better.
"grad school depression and anxiety"
I recommend that you check out this post. I don't think it's an illusion that a lot of people start to "feel crazy" when they start a grad program. I think graduate school causes mental distress for a lot of people.
"does not having a faculty position make you feel like a loser"
Not at all. :) On the contrary, I feel like I dodged a bullet, because I think I'd be miserable in 99% of faculty jobs. But everyone is different ... so you should carefully consider your options and think about what you want. But don't buy the academic line that a faculty position is the only job worth having. That might be true for some people, but it's certainly not true for everyone.
Presented without commentary:
"hate my dissertation topic want to quit"
"hate my research program and advisor"
"graduate school guilt"
You're not alone.
