Varma,
Good to hear from you.
Remember that ya gonna trip out a bit, because anxiety is like a nasty hallucenagenic drug in the mind, so dont beat your self up if you start getting nervous, just go with the rollercoaster. It doesn't last too long. At first it seems terrifying, but once you get going you may even enjoy it.
The biggest thrill is knowing you are strapped inside and what you experience is just a fleeting appearance. Trick is to let go of your hands from the bars, let the anxiety flow, you are quite safe, dont be afraid to let go. Then go get some chocolate ice cream and congratulate your self on surviving one of life's scariest internal rollercoasters.
You will find all you need, here on the website.
Good luck
Jack
