Are you taking Iron regulary now? It's highly normal to be having panic attacks after the scarey symptoms you describe. However all panic attacks are is an over-reaction to bodily symptoms which increases adrenalyn, which intensifies symptoms..then you think about those symptoms ..then they intensify,..until you reach aaaaaaahhhh panic attack! Just realize these are normal symptoms for anyone who would be going through your current medical problem and then focus on your breathing. Most of the time with panic, people breath shallow. Breathing in slowly and out slowly and easier ALWAYS works. It is the key. If you keep having symptoms...sweating, nervousness, feelings of out of body somewhat, don't worry, just accept that this is part of panic, focus on the breathing and try not to run just remember YOU are the safe place. Not your bed, the closet a dark room... You will be just fine. Millions of people have this everyday. It will get better.
