The safe sungazing method described on these websites can potentially help SAD. There are a lot of people reporting mental peace and help with fear and anxiety after sugazing.
please let me know if you are interested.. I can post many links on the subject of sungazing and exposure to sunlight including comments from some medical doctors.
I would love to have some more links on this subject if you have them! I know it has been awhile since you posted this, but I just now noticed this forum!!
