Someone elsewhere in the thread pointed out that it's truly hard to open up to another human, especially face to face. Even if you know they're a professional, it's awkward, it can be embarrassing, and there's stigma about a lot of things people ideally go to therapy for.
I mean, hell, there's people out there with absolutely terrible dental health who are avoiding going to the dentist because they're ashamed of it, even though logically, dentists have absolutely seen worse, and they're not there to judge, they're just there to help fix the problem.
There's no point bothering these poor volunteers/underpaid workers with my issues because they're inherently unfixable. Truth is, I should either suck it up or kill myself. Meanwhile with an LLM I will never feel like I'm wasting his time because he never gets tired of my blabbering about same shit over and over again.
