As someone who struggles with Anxiety, Depression, and PTSD “Meditations” by Julius Caesar has been a life changer.
Shows that they weren't always perfect, some of them were assholes, but others (notably Marcus Aurelius and Catho) lived the live they preached, and fought many battles (including literal ones) in ways that were different from their time.
Also, I don't think there's such a thing as a "stoic blind adherent", as self criticism is a big part of it. Examples would be Cicero, highly regarded by later Stoics as an egocentric asshole, or the early cinics, that molded stoicism for the future by criticizing it.
