"I suffered from depression since I was a teenager and by the time I got to around 30, I'd been on 14 different antidepressant combinations, years of talk therapy and depression really just slowly took everything from me. So TMS uses a magnetic field which stimulates activity within the brain, it stimulates the brain's own electrical activity and it works very gradually across multiple sessions. I go and sit in a chair that's kind of like a dentist's chair. They place the coil on your head. They kick the machine off and it's fairly intense the first few times that it goes off. Then I saw my tennis racket that I'd not used in 10 years. I was like, oh, I want to go and practice since that's on the tennis court. I couldn't believe the difference. It was like I was a new person."
