Hi, that is good news that it hasn't happened again. Maybe as much a "build up" of things going on at the time or feeling overwhelmed??
Good on you for pulling back from it though!!! If you're "back on track", yes, I'd agree with waiting for another appointment first.
If you can think about any reasons it might have happened and try to avoid/resolve those difficulties as/if they come up again that may help but otherwise times like that may come from nowhere, come AND go.
But you're OK now, GOOD news!!!
