Anxiety is an issue of 'fight or flight.' Anxiety is also a 'knowledge' issue. Our less evolved ancestors faced a cruel world that was getting crueler had they not done something about it. What did they do? They invented fire. Now look what the fire has done. They invented a wheel. A car. An airplane. Now look what they've done. Personal experiences? I have a few. Much more than I want to have, but you have to have experience and that causes people anxiety. But, that is the real cure for anxiety, knowledge and experience.
Again, you need to find the underlying cause for the anxiety.
Therapy works for many people, but depending on the severity of the anxiety, there are many different anti-anxiety meds out there...Clonazepam, Klonopin, Xanax, everything mentioned above,and more. But all of these are benzodiazopams and highly addictive.
