I finished therapy a while ago, after enrolling for it as a self diagnosed narcissist. After a while, my therapist asked me, in a frustrated tone, how I felt about him trying to be friendly, basically, and letting me know that he liked me. I suppose that's part of the therapeutic process, and I was supposed to internalise his esteem of me or something. Anyway, I was surprised and annoyed, because surely he knew that I don't care about anybody, him included? Why would he think that it mattered to me that he liked me? I'd told him several times that people's opinions of me don't matter, because I'm presenting a false front, and that the 'me' he saw was just another version of that. I don't know if he'd been hoping that I liked him, and would therefore be able to attach to other people as well.
The other thing that gets on my nerves is the insistence by therapists that mental problems are always caused by trauma of some sort, despite growing evidence to the contrary. Twin studies and the like seem to pass them by.
