if you haven't been adulting very well and now you're constantly sleep-deprived, your clothes aren't washed, your nutrition pyramid is inverted, etc, your problems are in a knot and trying to pull it in every direction at once will only tighten it.
focusing on one key issue (if you have poor sleep hygiene then I recommend starting there) will get one loop out of the knot, and now the knot is smaller, and the next loop comes out easier, and one day you'll realize you're fine.
