I must add if you haven't tried the medication route, it's definitely worth a shot. It has definitely reduced my anxiety significantly to where it's hardly a problem anymore. It took some time to find what worked, but I'm glad I finally got relief. Like you said, it really does feel like you are losing your mind.
I'm glad to help in any way. I know in my moments of anxiousness I sure would have liked some comforting advice. It sounds like you have the right attitude and I'm sure you'll kick your anxiety in the *****!
May the wind be always at your back.
