And chemotherapy works by making cancer patients throw up, and that is its primary function. This is how the noxious humors are expelled from the body, thereby curing cancer.
You are confusing a side effect with a methodology of treatment. Schizophrenics wouldn’t be cured by giving them some hypothetical memory-erasing drug, for God’s sake. What precise memories do you think cause schizophrenia? I have two schizophrenic cousins: one has been treated by a host of medications (with varying degrees of success), the other untreated. Both have been utterly crippled by the voices they hear and the paranoia warning them that their loved ones, people who are trying their hardest to help them, are murderers and pedophiles. One (the untreated one) at one point believed herself to be the daughter of Martha Stewart and her own cousin, who is younger than she is by about five years. She also thought certain singers were sending coded messages to her via their album covers, and thinks my six-year-old sister killed my brother and my mother. (God, I can’t seem to get away from this subject today.)
I would be fascinated to find out that she has memories that just need to be eradicated in order to remove such delusions from her brain.
Meanwhile, my other cousin is, thanks to absolutely tireless support from his father (despite threats this cousin has made to my uncle’s life), being treated, though the voices are still present and prevent him from doing things he used to love, such as playing music. But unlike my other cousin, this man accepts that he’s mentally ill and needs treatment.
Both depression and schizophrenia run rampant in my family, unfortunately. While certain tragedies do account for much of the depression, I have no doubt there is a biological/clinical element to it as well. I’ve suffered from depression as far back as I can remember, starting in extremely young childhood. Nothing happened to me specifically that made me depressed (until a bit later on in my life).
And let’s take another mental illness I’m fortunate enough to have. (Sigh. I really hit the jackpot.) Panic disorder. I’m not just afraid of elevators or crowds or planes. I get panic attacks out of nowhere, quite literally while I’m just sitting around in a perfectly quiet and relatively serene mood. Because I’m now terrified of the symptoms of these attacks (racing heart, adrenaline rushing through my body making me feel as if electricity is being applied to my nerves, an absolute certainty that I’m in some great danger), a cycle begins where just a slight elevation in my heart rate causes me to become hyper-vigilant, and this makes me more afraid, and the panic rises until I become unable to function. For days after an attack I’m left miserable and despairing of ever being free.
I’ve been helped tremendously over the last couple of years by certain meds that I’m not going to mention here (legal, but controversial and I don’t want to get into that argument) as well as cognitive behavioral therapy and other “tricks” I play on myself in order to distract myself from turning a low-level anxiety attack into a full-on panic hysteria that has, in the past, brought me to the ER certain I was having a heart attack. (P.S. I wasn’t.)
I’ve known bipolar sufferers who are in torment and who’ve tried to kill themselves. Very little has worked for them.
So yeah. No mental illness but schizophrenia my ass. Saying that “some things are overdiagnosed” is fine; illnesses go through phases and psychiatry is a relatively newish field. The brain itself is poorly understood even by neurologists, who still admit they’re not entirely certain why things work the way they do. It is a universe we have barely explored, and we are only just mapping some of the stars.
And mental illnesses aren’t the only ones that have gone through phases of utter misunderstanding. Yes, homosexuality was once in the DSM. Meanwhile, epilepsy (not a mental illness) was once considered possession by the devil; someone born with a cleft lip or palate was thought to have had a mother frightened by a rabbit. Things that aren’t understood are given incorrect explanations in an attempt to understand them–hell, people thought there was a face on Mars and that this is proof of a past civilization. People still believe in freakin’ Sasquatches!
Humans are notorious for making errors when trying to work through various theories. That doesn’t mean every theory is wrong, or that those who try to find the truth have evil intentions.
