You need to change your body and brain chemistry. All the things you listed ACTUALLY help si?ce they DO change you physically more or less drastically.
Thing is, that when you are a major fuck-up someone have to unfuck you since you are pretty much unable to unfuck yourself at this point.
Brutal truth: that someone will likely never come.
Brutal truth #2: Unfucking yourself takes time and you are a little modern shit that believes that everything, even major and serious things in your life, will come instantly and only after minimum of effort. Instant success, instant gf readily available for fuggenings after swiping her on Tinder, 300k starting after uni, promotion to CEO after a year, six-pack after 3 months doing gym 2 times a week, instant piece of mind after popping up a pill...
It's like you people are unable to grasp that some problems aren't easily fixable.
