(((lemmkins))) I know how you feel, I do the same sort of thing with phone conversations. Yet I've never had anyone I've talked to on the phone tell me I did anything wrong, even though at the time I would be sure I'd completely messed up.

If you feel up to it, I would suggest meeting these people again - I'm sure you'll find they didn't notice anything you felt you did wrong. But if you'd rather not, you should feel better about this with time.
