Hello Ninlow,You will find that what you are feeling is what so many in this forum go through...same feelings...same symptoms...common for anxiety and panic.
Here's the thing....fear drives the anxiety...not saying you will have a 100 panic attacks but if you did, you would survive everyone of them...I know it feels horrible but you will get through them...here's the key to either not having them or at least having less intense and or much shorter anxiety bouts.
The more you try to fight it, the worse it will make it...the more you try to figure it out, the worse it will make it....by learning a few coping skills like belly breathing and trying to stop the negative thoughts, the chemicals that are being produced will be less and flush quicker.
My best advice is to know that it will not kill you or cause you to shut down or go insane...roll with how you feel and it will ease much faster...some choose to sit or lay....if I feel weird and edgy like it's about to escalate....I get up and do something...walk...ride my bike...surf the computer...anything that will keep you from focusing 100 percent on how crappy it feels...I have overcome my panic attacks and most of my edgy anxiety by doing just as I said....roll with it and pay it as little attention as possible....the more attention you give it...the more it feeds it. Side note....do your best not to let it keep you from doing most of what you normally do because the list of things that you stop doing could grow and grow...you are more powerful than the anxiety, but if you let it have the upper hand...it can kick your butt....just know you are far from being alone in these symptoms....Best wishes...WM
