I am a *bad* PhD student that is about to graduate. How do I cope?

I have very good intuition, and am smart, but not studious. I got into academia for the wrong reasons a long time ago. I had a partner who was becoming an academic, and I felt I should be one too to be good enough. We broke up, and I was too deep into my degree to know what else to do. 

I just realized that I misunderstood an important result a long time ago, and have been acting on this wrong understanding for over two years. I am very lucky that my work is still correct, and only small parts need to be changed. I feel like a piece of crap, though.

So I am not good at what I do. If it is a life and death situation, I will sit down and learn a topic well. I will eventually forget everything, because I don't care about my field. I am missing a lot of the basics, but know how to wing it, so I am still floating. 

I don't know why, but at one point people started thinking I am some sort of a genius. Experiencing the disappointment that people go through when they realize that I am not devastates me. I don't want to be seen as anything. Then there are the sadists that have fun exposing me, humiliating and dominating me for being such a failure, and so on. So not only do I feel guilty, I also have very high external expectations and pressures that I have to work with. I tend to avoid everybody, which feeds into this who catch-22 thing. I just do not understand what anybody is talking about, and I don't care. 

I know that if I have to learn something to teach it, I will learn it well. I also know that I can apply things to the real world really well. Whatever I am doing right now, and whatever people value in academia are things I don't know how to deal with. 

I am very confident that I am going to graduate. I have a solid research plan, and am going to study well for my viva. I know I am getting my PhD. I am still terrified that someday someone will start digging, and then everybody realizes that I am a stupid nobody. 

My advisor doesn't give a fuck, and only wants to get things done. Their modus operandi is throwing shit until something sticks, and it seems that compliments is the shit for me. I don't trust anything they say. I have no idea how I am doing, and I don't think it is imposter syndrome.

Actually, this sounds like the definition of imposter syndrome. 

Until somebody in authority tells you that you must do major improvements, or kicks you out, your thinking that you will be a "bad" PhD is very likely wrong. There are always people who act in a condescending fashion, as if they are far smarter than you, and imply that you have done inferior work. ALL research has some failure. NOBODY's work is perfect, and all folks figure out flaws in their own work; what makes a good researcher is to work out the solutions. Everything sounds normal here except you are allowing your brain to run away with stuff that doesn't matter. 

Ignore everyone but your advisors, do your work, get finished, and when it's time move on to the next challenge, whether it's a postdoc, in academics, or elsewhere.
