I get this... Once in a while it wakes me up like a night terror... And other times I'll be in town I'll get hot and feel it coming on and sometimes I sit on the very unpleasant edge of it feeling as though I'm about to freak out and faint.. Or like a moment away from a head spin.... ...its like ya have to work so much harder to breath slow and remain calm... At times also like having to manually focus on breathing rather than the normal we don't usually think about our breathing patterns... I've been feeling with all sorts of pots slash autonomic dysfunction symptoms without official diagnosis...I'm not quite used to it and still adjusting and still searching for answers... Anxiety is just one of the symptoms or maybe just that I developed anxiety due to all the other various scary symptoms.. Its gotten to the point where I hardly go out... And even walking my son to school has become hard... Also due to exertion symptoms and getting hot etc.. Not just because I'll have a spell when out as this has happened a few times but has also become fear of having a spell. I've still gone out.. But here's the thing... Driving is the 'easier' part on my 'better days' but getting out of the car is another thing.. Actually getting out and walking around doing simple tasks has become more of a hard task...I could be standing there feeling 'ok' but then feel like I'm going to spin out at any moment... I'm 'inexperienced' at this 'pots stuff'... ...I also keep thinking I'll die any moment... Because it all feels so unnatural and is not pleasant or natural... I feel like my body is failing or has failed me.. I find this all very hard to accept that this is my life now...a physical social recluse because my body holds me back...I'm not one to be scared much but with this I cry sometimes cos I'm terrified of what next... Please share your story..
