B vitamins won't fix serious anxiety, but this supplement might, a doctor says

Dear Doctor Roach: I have a sensitive issue I’d like to ask you about. I’m a 79-year-old woman who’s dealing with a lot of stress and anxiety due to the recent suicide of my husband, the trauma of finding him, and all the trauma that followed. I’m in therapy, and I’m healthy and active. I don’t take any prescribed medications.
