Thank you Susan, I never really gave it a thought. But yes I get particularly gloomy during the shorter days and I am at my worst during Jan/Feb. I can recall that my last black mood lasted all of the winter and was hard to shake off. Here in the UK we get pretty depressing weather with continual grey skies and little sunshine during the winter months. I can cope with the cold but not with the lack of sun. My panic attacks are at their worst from late evening until early hours of the morning. Thankfully since taking the St John's Wort, I have felt much better in myself with lessening anxiety feelings - but I still need to be able to control my panic attacks more efficiently because when they do happen, I tend to go to pieces! Thanks again.
