Could I be under stress and not know it? Three months ago, My doctor put me off from work because I was feeling exhausted, having heart palpitations, and seizures. I do believe everything started because I was under a lot of stress at that time: working on my Master's degree, teaching middle school kids, and excercising too much (walking up hills, lifting weights, doing yoga every day, and drinking a lot of coffee to stay awake). But now I am just reading, watching TV, sleeping and going for short walks. I do not have worries at all because I am receiving money from my disability insurance, and I don't stay up all night thinking what is wrong for me; (I don't even have a husband or kids to worry about). However, the symptoms don't want to go away!!! Thank you.
