the mind is a powerful thing and has a DEFINET affect on the body. i'd be careful if i were you!!! speaking from experiance if you worry too much you put a lot of stress
on your body. you can make adrenalin put though your veins and too much adrenaline
can lead to anxiety
attacks which feel similar to heart attcks. (been there) you gotta find a way to help yourself relax and not worry so much.
