All this mindfulness & breathing bullshit that "healthcare" industry tries to push on people who are depressed and anxious
is just a Band-Aid. The root cause of people's misery is that society is built around capitalism and not human wellness. So they tell us all to breathe and meditate in order to cope in our fucked up society that is driven by capitalism and we are the capitalist slaves. How about we put human wellness at the forefront of society's priorities instead of money? we'd all be a lot less stressed out. mindfulness and breathing comes naturally when you're not a corporate slave.
Mindfulness and breathing exercises, relaxation exercises and such, are only tools, and insufficient on their own in terms of managing mental health and wellness.
On the other hand, you could limit the overall effectiveness of comprehensive treatment by not being mindful, and by not managing physiological stress through relaxation techniques.
If the tools are thrown out there by your company's HR, when the actual problem is poor working conditions (chronic understaffing for example), a cynical view is reasonable. Their purpose is to cost effectively minimize turnover.
Healthcare knows that what you're asking for isn't going to happen. Probably even get worse in the near future. Believe me, we really do know how fucked the system is.
We still aren't close, in the U.S., to having universal free healthcare.
Like many, many things that are good for people, eg: exercise, quality food... It's very difficult to get people to buy into the idea of simple things to try and help with stress/anxiety. No amount of counseling or prodding from professionals are going to get you to accept to do things that might be helpful. Until you decide to make it happen. Self motivation is absolutely necessary.
