When my partner enters an extreme anxiety phase it feels impossible to talk with him rationally. He gets tunnelled visioned, becomes obsessed with detail and doesn't seem able to see the big picture anymore. He gets so overwhelmed with issues that he stays up all night, he doesn't eat properly and he stops doing exercise, and it then becomes a vicious circle. He also refuses to take antidepressants although they calm him down and he won't take valium short term for fear of addiction. I want to share the load with him and support him but it's so difficult to get through to him and he refuses practical help. He's addressing some issues via CBT but I'd be really grateful for any tips or advice in how I can deal with this better, thank you.
