Hi all so glad I'm not on my own with this!! The last three weeks or so all these symptoms you have mentioned: light headed weak body as though I'm just gonna come to a stand still heart racing body shakin feel as though even talking is an effort!! I am so worried about it all it's ruining my life I can't sleep or anything I jus sit very still on y sofa scared to over do anything incase I have a heart attack!! I don't understand why this had just started?? My son has been diagnosed as disabled but this was like 6 months ago?? Can't think of anything else that is makin me anxious tbh!!!
