Wise answer fayerody. It is hard not to give an opinion based on our own history.

Here's my answer. Hope it helps !
The reaction of the friend and her husband is understandable, but they might get over it. Give them time to realize that you didn't mean it. I would tell them : it was stupid but I was on medication and my frustation (which was very real) was expressed in the wrong way. We all say things that mean something else. You said it in front of your friend ! You knew it was "safe" to talk nonsense. You probably needed some confirmation that you were attractive without a man hitting on you. This guy seemed a safe option. He might have made a compliment (even if it is unlikely in front of his wife), but he wouldn't have gone further.
Please consider this : maybe their reaction doesn't really have something to do with you. Maybe you put your finger on a wound, without knowing it. Why is your friend so upset about seeking counselling (who needs to be punished here ? Is this about your husband ?) ? Why does the husband of your friend react in such a rigid manner (guilt over a past episode ?). Wild guesses only, but think about it before taking all the blame.
