That can really depend. I've had both friends and family who have struggled with all kinds of issues. In every case I've seen so far, building a daily routine that involves getting out of bed and doing something that makes them feel useful/successful has been the cure.

It turns out that we're social creatures, and succeeding at doing stuff that benefits someone other than ourselves often helps us feel like life has meaning. That in turn helps us get over/process whatever shit we have behind us.

By all means, the LinkedIn post here is dogshit. I do, however, believe that for most people, getting back to work/school is paramount to getting better. Research backs me up. I'm on my phone now, but if you're interested, I'll dig up some studies when I have time.
