The boss is definitely not incompetent (he's incredibly smart), and I don't feel like he's a dick either. Maybe this is just my naivete from being fresh in the job market, but I really wanted him to like me, and one of the things that bums me out the most here is that now I obviously feel like he doesn't. I do feel like some of his criticisms were unfair, but like I said in my post I can't deny that some of the problems are genuinely my fault.

Thanks for the encouraging words though. I probably am being overly emotional about it. I have a lot of model uncertainty about my boss so I have genuinely no idea whether he would fire me.
