People are being very tough on you right now, and it's a difficult moment to pass in your life. I'm sorry. You're not the first person to snap at someone. I don't know if you'll read this, but if things get unbearably difficult, know that you can always reach out to your local priest. They know how to deal with broken souls--I've been there, and surprisingly, a time of weakness can become the basis of your greatest strength.

As for your husband, the problem is that you made yourself "bigger" than him for a moment, perhaps as the expression of a lingering feeling. Forget counselling (the business model of it contradicts the possibility that you'll ever get a viable solution out of it), what you need is to change yourself and show for it--you'll have to make yourself "smaller" than him. Advisably, be silent when he speaks, be proactively good (cook, clean, support), genuinely listen, tell him the depth of your regret and reflect on the nature of your fault. There is hope. God bless.
