It's of very little consequence to you. You suggest they try something /obvious/. It's reasonable to assume they might have considered it.
How is that going to be perceived positively as a suggestion? Do you think it possible?
For someone with major depression, maybe it's like suffering from major arterial bleeding and we suggest an band-aid because it "can help stop bleeding"
For me it was fixing a shower by myself that started that upward cycle.
For someone else it could be a single exercise session that leads to it.
It's always worth a try to encourage someone to take that first step.
Sure, absolutely. While keeping in mind it may not even be possible today. If it is the obvious way may be counter-productive. And the road to hell being paved the way it is, accidentally kicking the crap out of someone who is well and truly down is probably worth at least trying to avoid.
I am very sorry that you went through that. Your experience may not translate universally to those afflicted with the wide variety of ailments that are all referred to as depression.
