Mental illness is illness. If someone had a physical disability that made even going to physical therapy difficult, we'd expect more resources to be directed to help them get there to improve their lives. Or at the very least, we'd have enough empathy to say "damn, that sucks, and it isn't your fault alone."
I genuinely hope you never have to experience a mental health that gives you a real perspective on how that deep depression feels. But I also hope you show basic empathy to people struggling. It's a boomer mindset that's trickled down to us.
