One thing I find very informative when things like this are happening is seeing that - although everything feels awful And unstable - life is continuing, there is consciousness , I also find that I am able to still function. For example if it happens while I’m eating I find that “the body” still knows what to do, pick up the fork, put in mouth, take a drink, even with all the drama unfolding in my heart and soul and mind. Ultimately everything is ok , and ‘I’ am not needed.
