Try to think of something good then like your favorite food, think of a happy moment if yoiu have any..

one thing i do when I start to have a panic/anxiety attack is to find a spot on a wall and concertat on it, look at it and make it look like a flower in my mind , change my outlook on the place on the wall, it will make your mind think in a differnt way, if your mind is working the anxiety will go away faster.

it has really started to work for me over the past few weeks.. I have also started reading more it helps me to relax, and forget my life just for a few brief hours.
OR watch movies it does not matter what I watch just as long as I relax..

The more I relax the more I feel safe, the more I no lnoger feel the anxiety, or panic in my soul, ....
Just trying to help..
