Nah, it's everywhere. I don't think it's just women either, men too, just that it's invisible because they're told to not show their emotions. "Man up!" is probably a familiar sentence for some.
I personally have depression and anxiety. It's not financial related. I just feel a void inside and I don't know what to do. I can't work because even though I've been through therapies, I can't reason with my emotions. They get overwhelming. I know logically it makes no sense, but I still feel that pain and I can't find a way to make myself ok. Nobody wants a hyperventilating crying mess serving customers. But that's not the only problem, even at home I get overwhelmed and leave things undone. Anyway, not wanting a pity party, just stating blunt facts.
I've noticed some people are unhappy about materialistic or superficial things. Our consumerist culture coupled with social media showing artificial "perfect" lives and that creates dissatisfaction. What they need is good people around them and have fun experiences. Maybe get out and also do some good once in a while too. Nice memories are priceless, no amount of stuff is going to replace that. With things, less is more.
And then of course there's cases like mine with chronic stubborn mental illness, burdens, poverty, abuse, health problems, being worried for loved ones or putting too much on one's shoulders, and so on. I honestly don't know if things will get better for me, but I do have things to look forward to, and my life is pretty good overall. I just have "demons" inside of me.
