Diva,
I hope you are feeling better today. I know about the sad and worn out thing. Sometimes just getting through the day can be an effort in (and of) itself. At least I finally stopped blaming my (ahem) age for my being tired a lot. I've even had to admit lately that taking a short "power nap" when I'm able has helped to boost me through those mid-evening doldrums. I guess my pride was standing in the way of admitting that I needed those naps. hmmmmmmmm. Guess I should take my own advice about taking care of ourselves more often, huh? lol Just remember that you're waging a battle - and every battle has it's cost. With panic and depression, often times the cost is our bodies. It wears us down day after day and our bodies react by trying to defend itself (and the best way for the body to repair is through rest).
I try to approach things from a logical point of view most times. It helps me to put things in perspective. You take care of you. Your posts are great, and I agree. You help a lot of people. So stay strong, chin up and keep on - keepin' on. :)
