But... if what you need from her is support getting help then explain that to her point blank. I felt really bad when I found out how serious my H's anxiety disorder was at his low point. I'd talked to him, friends had talked to him.. I had asked his parents to help, but nothing we said or suggested was the answer. He was incapable of taking advice and changing anything until his anxiety was under control.
First, my wife never asked anybody for help for me. Well, she called one friend of mine ONCE but that was it.
Second, I no longer have any expectation she can or will be helpful to me. She has been very clear that she is 'gone'. She doesn't want to 'be a wife'. That is her code word for 'I don't want to be responsible for your feelings'.
Changing my diet, not drinking when I'm anxious and taking supplements has had a great affect on my attitude. I have enlisted a lot of men friends to be a support structure and that has been great for me.
I'm going to be all right. I need to let her go and move forward.
