I used to think I was depressed and I took St johns Wart at the advice of my mother, who was depressed and helped IMMENSLY by that. Only it didn't help me. At all. Come to find out I didn't have depression I have bipolar disorder II, and dr told me STOP taking St johns Wart, people who are depressed can be helped by that but people with bipolar disorder should not take St johns wart, it's bad for them. (I had thought I was depressed because I recognized my depression symptoms but I did not recognize my manic symptoms, leading me to think I was depressed because I thought my depression was the problem and my manic side was normal- everyone around me recognized both my depression and my manic side, but I didn't)
