I don't know what options are available to you for psychotherapy, but whenever I tell myself things like you are telling yourself, that's what I need. There are many hurdles to getting a PhD and then there are more hurdles to becoming a professor; your professor has surmounted all these hurdles, you have have surmounted some of them; in all probability there is much you can learn from him. Psychotherapy helps you learn to manage your own feelings about it.

You like your field and you have progressed quite a bit further than most people ever do, you are a success so far. I'd like to see you not give up at this stage. Life includes dealing with people we don't like, you can learn to deal with this.

My advice, at least give it a try before you make such a momentous decision.
