I feel at my wits' end. About 2 months ago, I was diagnosed with iron deficiency anaemia and have been taking ferrous sulphate ever since. I had no idea I was anaemic - went to the doc's as I'd had a massive relapse in anxiety and was finding the physical symptoms (shaking, extremes of hot and cold, nausea and vomiting) very hard to cope with. I hadn't had a relapse in a long time and honestly thought I was getting better - there was no real trigger.
Not long after starting on iron, I began to feel better - less anxious, sleeping better, no sickness, appetite returned, less tired and dizzy. Just last week I had a light period - enough to cause tummy pain but not much blood. Since then, I've been feeling anxious, restless, sick, and this morning I woke up at 4:30 
The GP thinks the aneamia was set off by a massive, haemorrhaging period I had back in January and I was basically getting weaker. My periods have been light and infrequent since then but this one last week was the first I've had since starting on iron. Could it be what's caused my setback? Any thoughts would be so much appreciated. I'm going on holiday in a few weeks and really thought I was making progress. If you feel rotten after your period, do you start to feel better again?
