Thank you for replying.
I agree that poor sleep has definately affected my cognitive abilities. I just was prescribed Dalmane for sleep this past week. I've been sleeping a little longer. But still feel the same. As for the diet recommendation I will look into that. I've already seen a cardiologist and he couldn't find anything except for a mild case of costiochondritis. I always get so worried when people say it sounds so much more severe than what the "normal" symptoms of depression are, but at the same time I've been tested for everything under the sun..and nothing has been discovered.
