Often when I am in a crisis, I also feel physically ill. I can't separate what's physical from what's emotional, so I just tell any medical personnel I come into contact with everything that's going on, and let them sort out which is which.

Right now, I am quite ill. I've been that way for days, barely able to eat, stomach cramps, what I'll tactfully call digestive urgency, dizziness, headaches, and now vomiting too. Besides depression, diabetes, and arthritis, I get migraines. Yesterday when I felt like one was coming on, I took the medication for it, and it did help, so there's a vote for physical. The doctor who prescribed it had said that if I take it for a headache and it doesn't go away, then it is something else, not a migraine. It did go away. But then that's when the vomiting started. And, although the headache part is still improved, I continue to feel awful in general. On top of this, I am emotionally fragile, and the slightest stress will trigger SI thoughts.

So is this depression or the flu? I don't rightly know, because sometimes they feel the same. One illness playing off the other, as Healing says above, is a strong possibility. I have felt awful for so long that if I were not already depressed, I think it would depress me.
