I've been reading the usual culprits (ie. Harris, Hitchens, Dawkins.... Dennet is on my todo list). I really like a talk about death by Harris.
Could you recommend books/talks that explore the subject of putting things into perspective, worrying about the usual things that much?
No, but I can recommend CBD oil for anxiety, sold at most health food stores.
"Cannabidiol is a compound derived from cannabis plants. It may help people with anxiety reduce their symptoms with few or no side effects.
A 2015 study concluded that CBD oil is a promising treatment for numerous forms of anxiety, including social anxiety disorder, panic disorder, obsessive-compulsive disorder, generalized anxiety disorder, and post-traumatic stress disorder."
