Nod, the challenge with it, like many things, is if it is appropriate/helpful/most useful for the actual situation at hand.
There are a whole class of issues, including PTSD, Anxiety, Depression (and related or semi-related stuff like perfectionism), that are not so much that the behavior or feeling is bad or wrong in any absolute sense - it’s just not useful or appropriate in the current environment and it is causing distress and life problems because of it. There are plenty of life circumstances where any of those states could be appropriate and would help the person. PTSD in the checkout line at the grocery store is clearly not one of them.
More nuanced research over time seems to be discovering it’s sometimes less about ‘smash the symptoms with a hammer forever’ (heavy medication) and sometimes it’s more about unblocking whatever is stuck that is stopping the person from learning and adjusting appropriately to what IS actually happening, and process whatever was going on before, so they can get out of the ‘stuck’ bad state.
This does include medication, among other things sometimes. Sometimes it’s also changing environment, removing bad influences/people, living support, etc.
Definitely not applicable to everyone. But applicable to a surprising number of cases.
