Poor you. Having suffered many many years I found cognitive behavioural therapy helped me massively. P5p is also a good supplement depending on how bad it is . A lot of anxiety is just a case of changing your mind set which is easier said than done but cbt is really good for this.
Do you know what brought it on? Has it been going on a long while. I take a really low dose of citalopram now as I decided against my belief that antidepressants are bad that it just balances the chemical balance and makes me feel more like me. I would seek some help lovely as it can become so consuming that you just can't see a way forward.
