100% agree. The "easy answers" are pre-requisites. You don't get to bitch about them not helping until you've actually done them and still feel bad. See also:

• When was the last time you ate?
• What did you eat, and why didn't it include a green vegetable?
• Are you getting enough sleep?
• Are you getting enough good sleep? (Sleep apnea is extremely common and also quicker and more convenient than you think to diagnose and treat.)
• Are you taking a daily multivitamin?

People dismiss these out of hand without actually trying them. Your body affects your mood a lot. I've had to deal with so many people both at work and in my personal life who were perpetually crabby because they never learned how to properly take care of themselves.
