You are much better than this, sweetie. And you will be much better than this again, too.
We all lapse. I'd be willing to bet every one of us here has been where you are ... I know I have. Beating yourself up over this is not constructive, at all. And hung over, you and I both know that your thinker ain't gonna work right anyway -- so your self-judgments are questionable, to my mind.
Honestly, if I were you I wouldn't even think about your husband's role in this right now. I would worry about climbing back on the bike and getting the pedals moving again, and let the therapist y'all are about to see help you two with this problem.
Drink plenty of water, stay in bed as long as possible, eat lightly and avoid greasy foods ... I guess we all know the drill by now, eh?
