Hi there,
I had severe anxiety and nervous breakdowns when I was younger. I'm only middle-aged now but back when I was having these problems it was not common to prescribe drugs. In fact, most of the drugs they have now didn't even exist.
But I was lucky in a way because I really don't think drugs are the answer. They can help temporarily but will do more harm than good if used on a long term basis.
So what finally worked for me? There are two things:
1. Passage of time and getting older. Unfortunately, there's no way this will help you quickly.
2. Breathing. I learned to breathe in a certain way to calm down and fight off panic attacks. I learned it on my own but now there are methods you can read about and learn from the web.
It may not provide all the immediate relief you need at times (though you may be surprised at how powerful it is!) but it's something that will help you all your life and will become more and more useful. And it provides so many other benefits.
I hope I'm not breaking any rules here by posting a link but you can get free instructions and an online demo at:

Good luck!
