I'm pretty healthy I think, at least in the aspects you listed since I get checked out every year. I'm glad it worked for you though. One thing I need to do more is exercise, so based on your experience at least maybe that will make a big difference.
The anxiety issues have been with me since I was a kid, but it gets more aggravated in certain situations, especially for the last couple of years. There are physical manifestations of it, even when I was a kid.
It is pretty debilitating especially when I'm in public. Or if I'm alone I just get totally trapped in my worries for hours.
