It frustrates me so much when very well-meaning people try and give advice. Advice that would work very well for someone not burdened with depression, anxiety, OCD, and insomnia. I'm a very intelligent person, I've done research, I tried so many things, but trying is the very hardest thing. When trying to brush my teeth is hard, trying your exercise routine is not a solution.
"Logic" doesn't help me, or I'd be able to logically maneuver my way out of depression and anxiety in the first place. Depression/Anxiety aren't logic deficits, they're chemical deficits.
Stop giving advice. Offer to help or walk away.
