Hi yellowkiwi (and a wave to White Rose!)
I understand what you are going through as I have been through the same and its awful to go through. White Rose has provided experienced support above including mentioning contacting your GP...
Just for your information there is an excellent thread topic about symptoms of anxiety ...its a big thread with people like yourself discussing their own symptoms...I really hope you find it helpful...The link is below
the forums are a safe and non judgemental place for you to post yellowkiwi
any questions are always welcome!
my kind thoughts
