Physical forms of illness can lead to depression, and vice versa. Yesterday I suddenly got very sick physically. I felt awfully weak and started throwing up. A medication I'm taking for pain (indomethacin) could be part of why, but I don't think there is just one cause. I've also been what I would call mildly depressed. I've been feeling too sore and weak to do much. Then, again, I think not doing much is making me weaker and sorer.

It's like a "which came first - the egg or the chicken?" situation. I wonder if other people who deal with depression find that it aggravates physical ailments? When you feel crummy, do you sometimes have trouble figuring out what is mental and what is physical, or what's causing what?
