Hi,
You haven't said anything about checkup results from a general medical examination nor metabolic studies done to check basic elements of your chemistry to be sure that your thyroids, parathyroids, and
adrenal glands are functioning properly among other systems.
You say you have become a vegetarian and cut out meat by 90%. Did you know that
Vitamin B12, which is an extremely important nutrient for good brain and
nerve health, may be lost if your diet contains very little meat or animal product material?
Low Vitamin B12 levels can affect the way a person feels in addition to how they think and process their environment. Seeing your doctor for a good physical examination will make you feel better in my opinion.
To be sure, if I were seeing you I would look into getting some basic metabolic studies to see where things sit before moving on to making diagnoses such as SAD or other types of psychologically driven states of mind.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Dariush Saghafi,
