Yes you can recover and even cure,its just another limiting belief to say you cab not cure...i know people who have cured themselves,meaning they don't feel any anxiety they used to feel
when in social situations.
Sa is just a string of negative beliefs and emotions whe have programmed in our minds at one point in our lives.
Our minds are a computer that can be reprogrammed, that's all
Now to get rid of the negative programs can be very difficult,but it can be done for sure,as long as you're willing to believe you can,you can cure from anything
