I actually trust psychiatry. It's not any more perfect than physical health treatments, but at least it gives you drugs that produce fast results.
What I truly hate is psychotherapy. Therapists are the most rotten, filthy, heinous mental health practitioners. They pretend to be your friend and blow smoke up your ass, while siding against you (like with your parents or "society") and stabbing you in the back. Not only that, they deliberately withhold medications from you, and blame you for "not being patient enough to wait until you feel better in the long run" when you ask for them.
Therapists are also cringeworthy morons; I mean, really, they actually believe that sharing your feelings is a cure for everything, from mild struggles at work to a crippling depression. While a few things, like the Oedipus Complex, can be cured by talking, things like depression are caused by a chemical imbalance, not a "lack of sharing feelings". And yet, therapists don't know that! And when you decide to share your real feelings about your troubles, therapists either turn around and laugh at you, or pretend they don't know what you're talking about. They are literally garbage!
