This comment raises a red flag for me. If my husband ever spoke about my alcoholism with family members, I would not be in this marriage. This has nothing to do with secrets, but a deep respect that should be present between two people in a commited relationship.
I strongly suggest you go to your dr and talk to him/her about your concerns. It sounds like the anxiety you're feeling about your health issues, is causing you a lot of distress. Find out what's happening and then you can begin to deal with things. I know it's hard to do, but it will help.
