Fortunately, professors only tried to demean me in undergrad. At the university I'm going to for grad school, they really don't do that. However, I don't think the grades are necessarily true either; some of them seemed to be artificially inflated in the past.

And by 'no amount of work will ever make me qualified', I mean even the work I'm doing now. I'm not sure how I will ever get a job. Part of the reason I went back for a doctorate was because I couldn't get a job (outside of an unrelated minimum wage job) with just a Master's. Not to mention that all jobs require experience and you can't get experience without a job. Maybe being a graduate assistant would count, but I have yet to get a graduate assistantship. I'm sure that has to do with not having a lot of experience and also being honest about my abilities (or lack thereof, in some cases).

I'm afraid to go to my peers for support since I'm not sure it's a good idea for anyone to know my weaknesses. And I'm not sure if people on the outside would fully understand.
