I've had eye twitching before while under stress. My father, who lived 700 miles from me, was dying from cancer, and I couldn't be there with him. My eye twitched so bad at times I could barely see and it was so dried out! I was there with him when he passed, and as soon as he did, the twitch was gone! That was 2 years ago. It is back now, but I don't see to have stress in my life.
I googled my twitch, and low and behold, it said fatigue was one of the major symptoms. Ah yes, the good ol' fibro fatigue! I know the fatigue has been bad lately, so it makes sense that that is what is causing my eye twitch. Gotta love fibro! ;)
