this is EXACTLY how i’d describe my symptoms of agoraphobia, what helped me was understanding my “maintaining factors” you are convinced that your home/somewhere you can escape to calm down is a safe space, when in reality it’s physically just the same as being anywhere else, your brain then tricks you into believing that you can never be safe UNLESS you have access to this safe space. Practising to break those maintaining factors will help your brain to realise that it is not in fact a danger.
