I have actually been blown away by the wind. All 200 lbs of me. I get so weak that my limbs just blow in the direction the wind takes me because I can't keep my muscles rigid enough.

"Just" Anxiety... Yeah. Maybe I am weird, but I have never met anyone that "Just" was anxious. There was always another source to the anxiety. PTSD, SPD, or just a bad atmosphere and the person's sixth sense is going off warning them. Bad memories triggering a physical reaction (PTSD) were the most common out of the people I have met who have overreacted to things.

If the cause of the anxiety is PTSD see a Mental Health professional and work through the memories to try to lower their impact on your life.

If the cause of the anxiety is SPD, see an Occupational Therapist to learn how to manage the SPD better or avoid those situations.

Sixth sense warnings are the hardest to explain to others, but it is better to listen to them and go do something else somewhere else. Usually just your unconscious mind picking up negative patterns in the situation and warning you to end the negative pattern before something goes wrong.
