Well I havent read the whole thread OP but its much more nuanced than your OP which people probably have already pointed out
You do need to be in a fit state emotionally and mentally to be able to take advantage of therapies, so sometimes people need meds to get them to that point
On the other hand GPs dont have much else in the treatment armoury, long waiting lists etc even if available. CBT is usually offered but that is not only ineffective for lots of people but is usually only 6 sessions, it cant touch the sides and I think its not that useful for people who are ND
Therapy is also not a fix all that its often made out to be on here, like as if you have therapy and then its all ok, some people cant respond, some people dont hvae the emotional insight, some people dont have the intelligence or cognitive functioning to manage therapies. The quality of therapists are really varied too, you can swap about for years trying to get one thats right and the NHS doesnt have that option for us.
Sometimes poor MH is simply like any other illness and needs chemical or physiological intervention and drugs is what keeps someone on an even keel
Sometimes its solely a lifestyle change thats needed but perhaps someone needs medication to get the motivation to exercise or lose weight or move house or job or any number of those changes that are needed.
I think meds are a really positive thing personally but I do also think that society needs to be structured in a more emotionally healthy way.
