Also keep in mind that when it comes to mental (and physical) health, Degree and Threshold matter a great deal.
In order to meet formal diagnostic criteria for Depression or Anxiety, symptoms have to be above a certain degree of intensity and they have to persist beyond a certain degree of duration. If we ignore those thresholds, then you’d be hard-pressed to find anyone in this world who is not dealing with some type of challenge.
My own personal view of health is that health is not the absence of disease processes, but rather the balancing of disease processes. Or to be more precise, the exact same biological processes that can be considered ‘disease’ when the system is in a state of imbalance, can be considered ‘healthy’ when the system is in a state of balance.
As for the implied question behind your question, consider this: There is a major category of the subliminals offered here that is called ‘HEALING’. If there is a category of subs called ‘Healing Subliminals’, then you clearly do not need to be 100% healthy to benefit from a subliminal.
The issue with formal mental health diagnoses and conditions, however, is that they have passed a certain level of intensity to the point that they are now majorly disruptive and have thrown off the corrective processes that usually serve to maintain ‘normal functioning’. So the point is that problems that have progressed to that point, need specific and focused attention.
Running a sub that supports having a clean and well-organized living space will always be helpful. But if you are suffering from a rat infestation and the house is currently on fire right now…well, you have some important and immediate steps to take beyond just listening to a subliminal.
‘Degree’ matters.
