What techniques can help with panic disorders?

Dear its very easy to calm anxiety . first of all take bath either warm or cold water use according to weather condition . then take a glass of your Favorited juice or water . lay down on bed enjoy glass but don,t use alcohol. then close your eyes just start to relax.
