Thanks so much to all of you who took the time to post your very good suggestions. My mind has become very dull and slow. I don't know what it's about. It really gets in the way of processing and problem-solving. Homework sounds like a good idea. I think I need concrete steps, because my mind can't handle abstraction lately. I can't hold onto insights or tools. I need to keep things very simple. It used to be easier to turn around negative thinking, and regain more lightness of being. I'm really very frightened to fall to such depths for such an extended period. I hate sounding so melodramatic. Still, it means a great deal to have your support and collective wisdom. I'll try to make good use of it.
