Your description of things kind of lines up with mine. My depression has lessened, and my wave are milder, but there is this constant drain on me. Early in the day I'm not working well cognitively, just not sharp, a bit anxious. The anxiety sticks with me throughout the day, it's mild and often bodily. I feel it in my legs it seems. The depression is nowhere near as heavy as it was, in facct I'd say it's mostly gone other than worries about the future, both near and distant, and being sensitive to stress.
How is your lifetstyle currenty, exercise, diet etc?
