Hello Slh and welcome.
I am really sorry to hear of your husband's issues, and the problems that it is causing for you and your family.
Anxiety is treatble, but the sufferer must participate in his own recovery. I hope that through your suport your husband will find the strength and courage to do so!
I agree with all of the above advice. Our members are awesome, and always ready with great support!
It would be great for you both to be in therapy. Individual for him as first priority...and for you both as a couple. If he will not go...then you need the support and advice on how to help him (and yourself and kids) and should go alone.
We have a great Resource Guide here with a lot of effective self-help ideas that he could try at home if he is willing. Steer him this way, and know that you both will be cared for!
Keep posting, and best wishes!
