Hi brennab
sorry to hear about your husbands anxiety - it obviously has a massive impact on your daily lives. You're definitely in the right place for advice and support which it sounds as though you need as much as he does. I'm not an expert so can't say he'll get better or suggest very much.
I'm sure someone will be able to give you pointers for support etc, just want to say people on here are always ready to listen and support so keep posting.
