Does anyone ever get the feeling that they're not anxious when you actually catch yourselves being anxious but you don't know what came first the anxiety symptoms or the anxiety ? Not sure if this is making any sense but I started feeling a little bit lightheaded and off-balance during the first week of May . Then three days later I start my cycle and start to feel worse off balance , lightheaded, heart pounding sweaty hands cold feet . And I'm struggling with it. Obviously the symptoms are not that bad when I don't think about it but I feel like they come out of nowhere and I get anxious or am I anxious to begin with ? I also went to the doctors and he didn't think blood test or necessary as I've had full blood work up six months ago he just perform neurological tests on me in the office and told me he didn't think it was anything serious as in the past I've had CAT scans and you name it I've done it . I'm still worried. Like how long will this last has this feeling lasted this long for some of you ? I keep thinking my brains not getting of oxygen or that I'm anemic because I have some type of illness that they're not finding . However blood tests say my levels are good . I had blood work done 6 months ago. The doctor said he didn't think it was that. But the life of health anxiety suffer ! Added) some sort of sinus pressure .
