It is complicated. Some people have mental health conditions which are always going to require medication. Some people have mental health conditions which are never going to require medication. And some people have mental health conditions where it depends on environmental circumstances. For that last group, lack of sleep/diet/exercise/etc can be part of the environmental circumstances which makes medication required, so fixing that can make medication less required, and may even go some way towards making it no longer required. Even if certain other things can make medication no longer required, sometimes it is still helpful in the short-to-medium term to give you the space to implement those things

There are serious concerns about iatrogenic harm in mental health due to overdiagnosis, misdiagnosis and overprescribing. Some people who are critical of medication are approaching the issue, not from some sense of superiority, but rather from negative personal experiences with the topic, for themselves and/or family members.
Taking psychiatric medication and being critical of it are not mutually exclusive-I myself do both. Medication is the least worst thing for me right now, but I hope one day I can solve some other problems in my life and remove some stressors and I may eventually wean myself off it. And simultaneously I believe a lot of people out there are being harmed by being prescribed the wrong medications. For example, the widespread prescribing of antipsychotics to adults and children without psychosis, by prescribers who are ignorant of the risks of brain atrophy [0] and who don’t communicate those risks to patients/parents. If you have schizophrenia, those risks may be the lesser evil; if you have a kindergartener with Aspergian traits and mildly violent behaviour, I’m not convinced it is. Maybe as a last resort once you’ve exhausted every alternative, but I know clinicians for whom risperidone is their first resort for such a patient not their last
