depression
"I have had Seasonal Affective Disorder for the past two years. I would feel depressed, anxious and even suicidal. However when I learned about this, I started taking them, and it works wonders! I am so happy now! Keep in mind that this may have side effects.... for me I have some trouble sleeping after it and your appetite decreases. For some people the appetite part is good because they need to lose weight but not for me. I am a bit worried because I am already a bit under weight and I don’t want to lose any more weight. But I guess I’ll see :) 
Thank you St Johns Wort!!"
