Hi Lettergirl, and welcome to 3FC's
I can honestly say, when I was on atkins I never felt better, it seems as though my depression was almost gone last winter and thats when I usually have it the worst, so I can not say I experienced the same as you w/low carb. I'm sorry you did experience the things you said. I would say talk to your doctor and tell him/her what happened, only he/she can suggest what would be good for you and your condition.
Good luck and please let us know how you make out.
