Glad to hear the training session went well. One thing you can do if you still feel you have doubts is compare the training session feed back to one before the stroke. If you find something missing or different, then that may be an area to concentrate on, if there is no significant difference then I would say you may not have lost as much as you feel. It would be best if the two sessions were of similar make up.

Also glad to hear the interview went well. Perhaps between the two of them next weekend or by Christmas you may have just a little bit more of your lost/temporarily misplaced confidence back, and can go into 2022 with not only an improved Crypto portfolio, but also an improved job confidence.
