Worth pointing out is that the mental health issues are only the symptom and not the cause, the cause should be adressed first rather than the symptoms.
How do you determine the root causes to be addressed?
Not to mention in the US many of these would have ended up on the streets...
To me the bigger cause of not enjoying it was/is external life getting back at you, notably worries about the future. I don't want to go to far into personal details, but I enjoyed it long enough to be confident I could indefinitely, if our society would be supporting it. This might be fine for a "robots do all the work" kind of future, but I have my doubts about UBI.
Anyway, after some point you most definitively want help to get out. As for mental health, there are probably reasons that made you retreat, but it likely caused new issues as well. But that's just one part of a well functioning support network.
It's the basis for the wildly successful and profitable "mental clinic" franchise business. There is one of those ( or two, or three, or four ) in front of every train station in Tokyo. For those who don't know Japan, take a look at a train map of Greater Tokyo and count stations, just for fun. You'll be doing that for a while. Then multiply the number by 2 or 4 to get to the number of "mental clinics".
Those are little more than drug dispensers run by legally authorized pimps with no medical expertise of any kind or a psychiatrist or psychologist anywhere on the premises, but anyone ( and millions do ) can "treat" their anxiety, depression, or insomnia, with half a dozen prescriptions a month. For good measure, they make sure to book appointments weekly in both the clinic near home and also the one near work. And maybe have a third one as backup.
What's needed is proper mental health services, on that you're spot on. And as another comment points out, to erase the stigma of suffering a mentall illness, so people don't use alcohol or these vending machine style clinics with no oversight to treat themselves.
That it is a problem and it needs to be treated everyone's perfectly aware of.
Also, on the good side, in Russia there are much fewer social obligations before people. As in Japan, if you didn't get a college degree to become a salaried employee in a huge company, you are fucked and no one respects you. In Russia, you can do a lot of things and with vast majority population being dirt poor and apathetic, social standards of what constitutes 'successful enough' are very low - some kid who dropped out of college to make $1500 on Upwork writting crappy PHP code at the age of 30 is a success story and his parents are proud of him - in Japan he would be a hikikomori because it would be a total shame to be in that state.
