> Chemistry trumps psychology
To nitpick: The mind is applied biochemistry. Psychology intervenes in the chemistry, like many other activities do. The goal of that is to solve the root cause so that your future levels will be maintained at the right level, instead of just forcing the level by sourcing the respective chemicals externally.
A good rule of thumb in biology and particular any kind of hormone production and balance is "use it or lose it" - if you start regularly receiving something externally, internal production will scale back and atrophy in response, in many cases permanently.
Psychology can change neurochemistry but only in certain limited ways. Many people are on antidepressants long term because that's the only thing that works for them. Taking antidepressants is already stigmatized enough. People should just do what makes them feel best over the long run. Your rule of thumb does not trump hard-won personal experiences.
We don't really know how SSRIs work, but there's some evidence that it's through desensitizing serotonin receptors, not directly addressing the lack of serotonin. If so, "use it or lose it" doesn't apply; long-term adaptation is the point, and SOMETIMES does persist after quitting.

There are ways to "hack it".
For example, ~6 months ago I started trt (testosterone replacement). It was the best decision health wise ever. I feel way better psychologically, first time in my life I managed to stick with cardio training for so long (before 3 months was the most). There are other benefits too.
So what about the "loose it" part? Well there is a hormone called HCG one can take a twice a week to trick one's balls into producing some natural testosterone. Its use prevents atrophy and infertility.

Very basic and very often wrong rule, so take it with a grain of salt.
Insulin for example is the opposite. "lose it then use it" would be a general rule for type 2 diabetics where insulin resistance commonly due to weight gain is the primary problem. Losing the weight leads to better uptake and usage. For a type 1 "lose it then use it" you typically lose the ability to produce insulin to an an autoimmune disorder, then are stuck using insulin for the rest of your life.
The body itself typically attempts to main homeostasis, but at population scales this is something that is going to have a massive range of ways it shows up. Evolution, at grand scales, doesn't care if you survive as long as enough of your population survives and breeds. At the end of the day you might just be one of those people that was born broken and to work properly you need replacement parts/chemicals. A working medical system should be there to figure out which case is which.
