My anxiety has me similarly stuck. I've been able to somewhat push through to get to the store when needed, but only really because of nicotine cravings, and I am freaking out the whole way, even with supposed anti anxiety meds. My body is stuck in fight or flight mode, everything is scary and confusing. I have gone through periods of anxiety, social phobia and panic attacks intermittently for most of my life, but the catalyst for me here was the sudden and unexpected death of the person who helped to consistently anchor me. Since then absolutely everything triggers me and it's not easing up, no matter what I do.
I feel for you. It is hell to battle with our own brains every moment of the day.
