Inspired by a post I made on Instagram, here's 25 minutes or so on the difference between feeling OK and actually being OK.  The highlights:

Your anxiety disorder has you in the bad habit of scanning and evaluating your state all the time
Your anxiety disorder has you interpreting how you feel through a distorted lens of fear and misguided threat assessment
You then make the mistake of nailing your assessment of how you FEEL, so your assessment of what you are capable of doing

You do not have to feel OK, to be OK.  You must be aware of the scanning and evaluating habit, and you must be aware of the mistake of equating how you feel to what you are capable of doing.  You must ACT even when feeling less than OK. You must show yourself through experience that thinking that you are not OK is incorrect, and that you are able to manage and live a normal day even when feeling badly.  The experience of doing this repeatedly will help eliminate the mistake you have been making and break the scanning/evaluating habit you have formed.
Remember, action is required.  You cannot simply choose to believe that you are OK, you must ACT to show yourself that you are really OK regardless of how you feel.
Going through this process will teach you lessons about tolerating and managing the distress that are bound to impact every one of us from time to time.  These are lessons that go far beyond anxiety recovery and will serve you will forever.
