That's the key to remember, it does get better. You can overcome it. But since you are now hypersensitive to certain physical conditions, you sense everything as being a crisis, right? Take it slow, realize that overcoming anxiety is a lot like getting a master's degree, it takes time. But as you go along, it gets easier to cope with it.
And as you learn to deal with the symptoms and they go away for a day, a week, a month, or a year, realize that we will sometimes get those little setbacks because of holiday stessors, a tough time at work, kids, etc. It's normal to have a setback.
Take the first steps in understanding what happens with us when our bodies misinterpret something and kick in the "fight or flight" response. Understand what symptoms we get when we have adrenaline coursing through our bodies. And lastly, something that helped me a bit is that there are adrenaline junkies out there that need the constant "high" that adrenaline gives them. Imagine that, some people thrive on elements of the anxiety response that we are fighting.
That little tidbit helped me understand that this isn't going to kill me, some people seek out this feeling that I have, and that it does go away - with time and a little education.
