I have had a cough for a few weeks. Thought nothing off it- had normal lemon, honey ectc. I think It's turned into a chest infection but I really am finding it hard to breathe I will have a conversation and be out of breath. My heart is being so weird and skipping beats & I am just all heady I have a very demanding job teaching dance and I can't get through an hour at the moment without my whole body telling me noooooo & I've been fine up until now . My heart feels so tight... I have doctors tomorrow but am suppose to be flying to Ireland Friday hope I can still fly!
