I suffered from overwhelming panic attacks and anxiety. I had tried therapy and medication, nothing worked. I had PTSD from an abusive childhood and my first husband was also abusive. The retreat work removed the panic attacks but I saw clearly I had to let go of negative conditioning and relationships with self and others to be truly free. So most of my work has been centered around living a good life and developing healthy relationships with myself and my circle of influence.
I sat through my panic attacks until they wore themselves out and left me alone and I haven't had a panic attack since 1995....but this is always subjective, it is up to individual conditioning and understanding. But I know several other meditators that let go of their panic attacks this way....I also lost my night terrors which I suffered from since a small child.
I still suffer normal anxiety, which we all suffer from...hahaha <3
