I don't know anything about ECT, but I remember in my psychology classes the professor was talking about suicide and he said that more suicides happen in spring than any other season because when people are so depressed from the winter, they don't even have the energy to think about or take action to commit suicide. When they start feeling a little better from the spring weather, they have more energy to devote to that.

I wonder if it could be the same thing for ECT? You may be improving and that may be the reason you are feeling more instead of just being numb. It may take some more treatments and improvements for those feelings to become more and more positive, but I wouldn't necessarily consider your current condition as a negative thing. You want your husband by you for safety reasons, so I think you are on the right track in taking care of yourself.
