Hi LSF
Are you in Therapy yourself for your anxiety?
Hmm - Is there a self-help group for relatives you could go to? This could bring you some relieve.
It's a good thing that you're husband is trying to get better. It can be hard to see your H suffer, but always remember: You can only help him if you're okay yourself. Please, don't overburden yourself. There's only a limited set of things you can do for him.
Can't you do anything with your friends which doesn't cost anything? Like going for a walk
Take care
