I am suffering very badly with a constant headache, sensitivity around head, eyes, jaw, am hot, weepy and have extreme lethargy. I think this is all linked to my hormones, I feel like a less extreme version of this before my period. But I've been breastfeeding for a long time and haven't had one. Perhaps I'm about to get it. this is coinciding with my return to work so perfect timing. Does anybody else ever feel like this and how do you plough through? I feel like I can barely function and the timing is making me very anxious. It's been 6 days now
