Seth Wilson, a 41-year-old sommelier in Chicago, has been dealing with depression and anxiety since he was 13 years old. Wilson learned to live with his panic attacks until his mother passed away and they gradually got worse. He had been on some kind of antidepressant or anti-anxiety medication for over a decade, but he wasn’t getting the help he needed. One day last spring, he went to a Field Trip Health clinic overlooking Lake Michigan, put on eyeshades, headphones, leaned back in a comfy zero-gravity leather chair and got an injection of the dissociative anesthetic ketamine. Within seconds he was blasted to the cosmos and entered the event horizon of a black hole.
