Honestly, a lot.As someone who has been to countless psychiatric clinics and hospitals of the course of a decade and ironically also studying medicine in general, I feel like I'm at least somewhat qualified to speak out against all the bs in this field.
Issue "1": Psychiatry is fundamentally flawed. Guess what the main goal of psychiatry is? Well it's not actually making you happy! It's keeping your pulse. That's it. Actually helping you enjoying life is more like a cool bonus they might as well get from time to time. But they're not professionally obligated to do so. Yes it's the moral thing to do but this brings me to my next point.
Issue "2": Malpractice. It's not like in other fields of medicine. With anything else, it's always clear how your work is affecting your patient through easy monitoring, so malpractice is usually very difficult to get away with. Psychiatry however, no one gives a damn. Their job is keeping you alive, that's it. Oh you're too numb to every emotion? Meh. Oh you're having horrible side effects? Trade them for another medication with slightly more tolerable side effects. Oh your doctor broke confidentiality with your family? It's okay he can do that "fOr yOuR SaFeTy". Oh your doctor is basically milking you for money while keeping you drugged like a zombie? Eh, sounds like a you problem. It's a disgrace how much most "professionals" can get away with. But can you blame them? My next point is...
Issue "3": It's expensive, very expensive. I may not be from the US but it's expensive worldwide and rarely covered by insurance or minimal coverage at best. Maybe they'd get you a psychiatrist with a waiting time of 6 months or some bs. And that's just seeing the psychiatrist, medications are their own whole other level of expenses. And since most psychiatrists like to zombify you by drugging you to the limits of human consumption, the bills add up. And that brings me to...
Issue "4": The medications are crap. Firstly, most of them just make you numb to the point you can't have any thoughts, technically "fixing" you negative thoughts problem. Oh you have bad thoughts? Let's take away your ability to think then! It's like going to a doctor with a bad cut on your hand and he just amputated it. Problem solved right? Then of course there are the side effects. Almost all of them have so many side effects and the worst part is that it's so normalized. Imagine taking a paracetamol for headaches for a while and then suddenly feeling like you can't sleep less than 12 hours a day and when you mention it to people, they just say "oh that's normal you get used to it" why am I supposed to get used to it? Why am I forced to trade one issue for another? And then you constantly change medications back and forth and back and forth, until you just get an ounce of normality for a couple weeks and then it stops working.
So tldr, psychiatry is a load of bs and I doubt that'll ever change.
