Hi i'm a 45 yr old female , who is very confused with what i have been experiencing for around 5yrs now. At home and around the house i feel fine, but once i go out onto the street i feel very dizzy , and even worse if im in a queue ( shop or bank ), i get hot and sweaty , and lean onto things to stable me and my heart starts racing and i start to shake a little, i have had to walk out of places in fear of me fainting, i do not go anywhere on my own anymore, i would be so so grateful if you could help me as to what it might be. It seems to be getting worse , and i have not yet spoken to my own gp about it. many thanks annette.
