Fuck Freud. BUT, I do believe that zizekian hegelianism is useful when trying to uncover people's motivations and traumas.
It is highly idealist, but it is also a very creative process that helps to explore the problem space. The final solution will probably not be a hegelian dialectical moment, but it was discovered via negation, and shit like that.
Like someone is telling me their problem and why they believe they arrived at it, then I try to inverse their proposal, "what if the opposite were true" kind of move. If it is true, I then try to negate it and go back to the first point, because it might have a kernel of truth. Then I gather all the "discovered reasons" which might be contradictory and try to ask, what if they are true simultaneously.
It's very much like cold reading, but I've found it to be a very helpful tool. I'm not a psychoanalyst, nor a psychologist, nor anything. I don't think people should take psychoanalytical tools into a rigid and formal scenario, I would consider that scientism. But I would also consider scientism to dismiss psychoanalysis as useless. Talk therapy is extremely important, especially in our alienated society. We frequently need people to force us to realize what we don't want to admit to ourselves.
I went to a medium that spoke with angels. It's obviously bullshit, and I'll skip the story of what led me there. But the point is that this medium was evidently fulfilling the role of a psychoanalyst, except much worse because "the angels" were giving me extremely shitty advice, instead of listening and asking me stuff, like a therapist should do. I once went to a strip club, I'll spare the story as well. At one point, a girl was "dancing" with me / entertaining me, I'm gay so I was uninterested, so we were just talking (and occasionally grabbing her boobs lmao). I mentioned in passing something I was worried about in my personal life (work, or something), and she immediately latched onto it and started asking questions. It became very transparent what was going on, she didn't even look genuinely interested, she was trying to give me mental therapy! Similar to the medium, very unprepared, in a ridiculous environment, and not really a place to ball your eyes out.
Anyways, I'll leave that last bit as food for thought.
