ive tried easycalm some years ago and found it a bit helpful. The techniques he shares are law of attraction based, so you just try to avoid negative news etc and focus on your progress. He takes it very little, he suggest doing little exposures everyday that push you out of your comfort zone.
The anxiety technque he shares has a bit of meditation/mindfullness touch. When you have an anxiety attack just observe the subject, as if you were a medical professional who jsut notices the symptoms without being upset about the anxiety or analyzing it. Just observe the sesnation "now i feel tightness in my chest, my heart is beating etc.". You do it until you feel calm.
So its a mix of techniques and a exposure plan which isnt to scary, just little tiny steps. I didnt have much sucess with it, but i wasnt really commited back then. All in all Jon Mercers system for anxiety is worth a try, because if you do the things everyday you will notice positive benefits.
I also buyed the social anxiety secrets, these ar little mind games you play in your head while in a social situation. There are 10 different strategies. I dont remember them all but one i like was this: imagine you are a CEO of the place you are now in(supermarket, place of the party, workplace .. whatever) and you have a 1.000.000.000 Dollar check in the bag. Your goal is to find the person who wins the 1.000.000.00 dollar check, so your looking for positive traits in other persons rather than the negatives which you may mostly see. You are the judger, the people dont judge you because you are the CEo, you own this place you are in.
When you leave the social setting just imagine you take that check out of your bag and give it to the person who mostly deserves it.
The social anxiety strategies are also worth a try. Its a nice tool to have.
Hope this helps
