Do you and your husband ( or significant other) really ever talk about your diagnosis?
I know for me, my husband rarely spoke about it. I feel this was because he never really came to grips with the idea that I was 'sick'..... I have no doubt that by not talking about it, I would be 'ok'. The fear of losing someone can be a powerful influence for not talking about a subject.
Having a conversation, I feel, admitting that sometimes how scared we are can give them a chance to say how they feel as well.
